The '''Seattle Mariners''' are an American professional [[baseball]] team based in [[Seattle]]. The Mariners compete in [[Major League Baseball]] (MLB) as a member club of the [[American League]] (AL) [[American League West|West Division]]. The team joined the American League as an [[expansion team]] in [[1977 Major League Baseball expansion|1977]], originally playing their home games in the [[Kingdome]]. Since July {{baseball year|1999}}, the Mariners' home [[Baseball park|ballpark]] has been [[T-Mobile Park]], located in the [[SoDo, Seattle|SoDo]] neighborhood of Seattle.

The "Mariners" name originates from the prominence of [[seamanship|marine]] culture in the city of Seattle. They are [[List of baseball nicknames|nicknamed]] the '''M's''', a title featured in their primary logo from 1987 to 1992. They adopted their current team colors – [[navy blue]], northwest green ([[teal]]), and [[Silver (color)|silver]] – before the 1993 season, after having been [[royal blue]] and [[Gold (color)|gold]] since the team's inception; the original colors continue to be used in alternate uniforms. Their [[List of Major League Baseball mascots|mascot]] is the [[Mariner Moose]].

The Mariners first fielded a winning team in 1991, and reached the playoffs in 1995, 1997, 2000, and 2001; the most successful period in franchise history. Led by [[National Baseball Hall of Fame|Hall of Fame]] players [[Edgar Martínez]], [[Ken Griffey Jr.]], and [[Randy Johnson]], the Mariners clinched their first playoff berth in {{baseball year|1995}} when they won their first division championship and defeated the [[New York Yankees]] in the [[American League Division Series|ALDS]]. Martínez's [[The Double (Seattle Mariners)|walk-off double in Game 5]] drove Griffey in from first base to win the game in the 11th inning, clinched a series win for the Mariners, served as a powerful impetus to preserve baseball in Seattle, and has become an iconic moment in team history. They would win their second division title in [[1997 Seattle Mariners season|1997]].

After Griffey, Johnson, and [[Alex Rodriguez]] left the team, the Mariners, bolstered by the signing of [[Ichiro Suzuki]], won 116 games in [[2001 Seattle Mariners season|2001]], which set the American League record for most wins in a single season and tied the [[1906 Chicago Cubs season|1906 Chicago Cubs]] for the Major League record for most wins in a single season. Following the 2001 season, the franchise entered a long period of mediocrity and would not make the postseason again until [[2022 Seattle Mariners season|2022]]. They won their fourth AL West division title in [[2025 Seattle Mariners season|2025]], their first title since 2001.

The franchise has finished with a losing record in [[List of Seattle Mariners seasons|30 of 49 seasons]], {{As of|2025|lc=y}}. The Mariners are the only active MLB franchise to never appear in the [[World Series]], holding the sport's [[List of Major League Baseball franchise postseason droughts#World Series appearance droughts|longest active World Series appearance drought]].

{{As of|2025|alt=As of the end of the 2025 season}}, the Mariners' all-time win–loss record is {{Win–loss record|w=3,689|l=4,022|t=2}} ({{Winning percentage|3689|4022|2}}).<ref>{{Cite web |title=Seattle Mariners Team History & Encyclopedia |url=https://www.baseball-reference.com/teams/SEA/index.shtml |access-date=September 30, 2024 |website=Baseball-Reference.com}}</ref>

The team avoided finishing in last place in the AL West [[1977 Oakland Athletics season|by half a game]]. The Mariners did not post a winning record or finish above fourth place during their [[1990 Seattle Mariners season|first fourteen seasons]]. In [[1979 Seattle Mariners season|1979]], Seattle hosted the [[1979 Major League Baseball All-Star Game|50th MLB All-Star Game]] at the Kingdome.

Before the [[1993 Seattle Mariners season|1993]] season, the Mariners hired manager [[Lou Piniella]], who had led the [[1990 Cincinnati Reds season|Cincinnati Reds]] to victory in the [[1990 World Series]].

The Stanton/Dipoto/Servais era was characterized by two competitive phases. In the first phase, the organization tried to contend for a championship with the existing core of [[Robinson Cano]], [[Félix Hernández]], [[Nelson Cruz]], and [[Kyle Seager]]. The team came close but ultimately missed the playoffs. Following the [[2018 Seattle Mariners season|2018]] season, the organization pivoted to a rebuild, trading several players for prospects. Following a fallow period of [[2019 Seattle Mariners season|2019]]–[[2020 Seattle Mariners season|20]], the team returned to contention in [[2021 Seattle Mariners season|2021]], winning 90 games but falling short of the playoffs. In [[2022 Seattle Mariners season|2022]], with a new core including [[Julio Rodríguez]], [[J. P. Crawford]], [[Cal Raleigh]], [[Luis Castillo (pitcher, born 1992)|Luis Castillo]], [[George Kirby (baseball)|George Kirby]], and [[Logan Gilbert]], the team reached the postseason for the first time since 2001.

In August [[2024 Seattle Mariners season|2024]], Servais was fired after blowing a ten-game lead in the AL West over the [[2024 Houston Astros season|Houston Astros]] and having the team fall back to .500 and was succeeded by former M's catcher [[Dan Wilson (catcher)|Dan Wilson]],<ref>{{Cite web |last=Kramer |first=Daniel |date=August 23, 2024 |title=Mariners dismiss Servais as manager, name Dan Wilson as replacement |url=https://www.mlb.com/news/scott-servais-fired-as-mariners-manager |access-date=2024-10-08 |website=MLB.com |language=en}}</ref> but he team again missed the playoffs by one game. In [[2025 Seattle Mariners season|2025]], the Mariners won their first AL West title in [[2001 Seattle Mariners season|24 years]]. In the [[2025 Major League Baseball postseason|playoffs]], they defeated the [[2025 Detroit Tigers season|Tigers]] in the [[2025 American League Division Series|ALDS]] in five games and had a 2-0 [[2025 American League Championship Series|ALCS]] lead against the [[2025 Toronto Blue Jays season|Blue Jays]] until they ultimately blew a 3-1 lead in Game 7. This was the first time the franchise ever played in a Game 7, also meaning this is the closest they have ever been to a World Series appearance.

==Uniforms==
[[File:Ruppert Jones 1978.jpg|thumb|[[Ruppert Jones]] in the team's first uniform design]]

=== 1977–1980 ===
The Mariners' original colors were blue and gold, the color scheme previously used by the Seattle Pilots and its successor Milwaukee Brewers. For the first four seasons, they wore white pullover jerseys at home with the team name in front and numbers on the left chest. The "M" in "Mariners" was shaped to resemble a [[trident]]. On the road, they wore baby blue pullover jerseys with the city name in front and numbers on the left chest. The lettering colors were blue with gold trim, though in the 1977 season the trim on the road jersey was white and the "Seattle" wordmark appeared smaller. The trident logo was added to the left sleeve prior to the 1979 season.

The cap was all-blue and featured the gold trident logo with white trim.

===1981–1986===
The Mariners made some subtle changes to the uniform in 1981. The trident logo was replaced by blue and gold racing stripes on the shoulders, and the lettering received an extra blue outline. The number font also changed from rounded to block style. In 1985, the road jersey color was changed to grey.

The cap logo also featured a slight update of the trident logo, changing its color to blue, along with additional outlines and a white star background, a logo first used for the 1979 All-Star Game.[[File:1987 Mother's Cookies - Scott Bankhead.jpg|thumb|upright|[[Scott Bankhead]] in the uniform design from 1987 to 1992]]

=== 1987–1992 ===
In 1987, the Mariners changed its uniform style to traditional buttoned tops and belted pants. Both uniforms incorporated blue piping and a block "Mariners" wordmark in blue with gold and blue outlines. The numbers remained blue, but eliminated the trim outlines.

The cap logo was changed to a gold "S."

===1993–present===
The Mariners donned their current uniforms in {{mlby|1993}}. The white home uniform originally featured "Mariners" in navy with trim in a shade of [[Teal#Teal green|teal green]], exclusively named "Northwest Green" for the team, and featured the "compass rose" logo atop the "M."<ref>{{Cite book |url=https://img.mlbstatic.com/mlb-images/image/upload/fl_attachment/mlb/mdp226e3cw9r2wo37o0t.pdf |title=Seattle Mariners 2021 Information Guide |publisher=Seattle Mariners |year=2021 |pages=189}}</ref> The grey road uniform originally featured "Seattle" in navy with Northwest Green and white trim; in 2001, the compass rose logo was added in the middle of the "S." In 2015, a silver inline was added to the wordmark of both uniforms, which was also applied to the block letters and numbers. The primary logo is applied to the left sleeve.<ref name="Mariners2015Uniforms">{{Cite web |last=Novak |first=Paul |date=January 23, 2015 |title=Seattle Mariners Unveil New Uniforms |url=https://emeraldcityswagger.com/2015/01/23/seattle-mariners-unveil-new-uniforms/ |access-date=February 11, 2018 |website=emeraldcityswagger.com |publisher=Open Publishing}}</ref>

From 1997 to 2000, the Mariners also wore sleeveless versions of their primary uniforms, accompanied with a navy undershirt.

The Mariners have also worn Northwest Green alternate uniforms at different points in their history. The original version was unveiled in 1994 and had "Mariners" in silver with navy and white trim. The next season, the white trim was removed<ref>{{Cite web |title=Seattle Mariners Uniform - Alternate Uniform - American League (AL) - Chris Creamer's Sports Logos Page |url=https://www.sportslogos.net/logos/view/k8ubhh09gpbew6c3ohqenfxge/Seattle_Mariners/1995/Alternate_Uniform |access-date=2024-10-08 |website=SportsLogos.Net}}</ref> to improve visibility. The Mariners did not wear green uniforms from 1997 to 2010, after which it became a regular part of their uniform rotation. Formerly worn on Friday home games, the Northwest Green alternates are currently worn on select Saturday home games and on road games in which the home team wears either navy or black uniforms.<ref name=adam/><ref>{{Cite web |last=Divish |first=Ryan |author-link=Ryan Divish |date=October 20, 2010 |title=Mariners going green...with their jerseys |url=http://blog.thenewstribune.com/mariners/2010/10/20/mariners-going-green-with-their-jerseys/ |url-status=dead |archive-url=https://web.archive.org/web/20150201021742/http://blog.thenewstribune.com/mariners/2010/10/20/mariners-going-green-with-their-jerseys/ |archive-date=February 1, 2015 |access-date=January 31, 2015 |website=[[The News Tribune]]}}</ref>

The navy alternate uniform originally replaced the Northwest Green alternate in 1997 and featured the team name in silver with Northwest Green and navy trim. In 1999, the alternates were updated to feature the city name with the "S" behind the compass rose logo and silver piping; this became their road alternate the following season after a corresponding home navy alternate was introduced. In 2003, the silver piping was removed and the letter and number fonts were changed to match the wordmark. In 2012, after the Northwest Green home alternates were brought back, the navy uniforms were tweaked anew, this time with the city name in front and stylized serifed letters instead of the normal block letters. In 2024, the names were changed to block lettering. It is now worn on most road games, though they have also donned them at home on occasion.

A navy blue cap that features a ball and compass rose "S" logo is paired with the home white, road gray, and navy blue jerseys. A variation of this cap with a Northwest Green brim is worn with the home alternate jersey. In 1994, the Mariners also wore Northwest Green caps with navy brims, and in 1997 the team wore a navy cap with grey brims.

In January 2015, the team announced a new alternate uniform to be worn for Sunday home games.

In January 2019, the Mariners announced a new home and away uniform to be worn during [[spring training]]. The jersey has a design similar to their home white jerseys but features a powder blue throwback to the team colors during the 1980s. The cap has the usual navy blue color, but with a logo that features the signature [[compass rose]] and with a large M in the center.

For the [[2023 Major League Baseball season|2023 season]], MLB and Nike have instituted a "four plus one" model for team uniforms, consisting of a home uniform, away uniform, two alternate uniforms, and a [[City Connect]] uniform featuring "color schemes and logos that pay homage to a team's city."<ref name="Nike4plus1uniforms">{{Cite news |date=January 16, 2023 |title=Cardinals Warm-up Live: Cardinals will wear City Connect uniforms in 2024 |url=https://www.stltoday.com/sports/baseball/professional/cardinal-beat/cardinals-warm-up-live-cardinals-will-wear-city-connect-uniforms-in-2024/article_66df167c-d6bc-54be-b859-c0301658b2c6.html |archive-url=https://web.archive.org/web/20230116174330/https://www.stltoday.com/sports/baseball/professional/cardinal-beat/cardinals-warm-up-live-cardinals-will-wear-city-connect-uniforms-in-2024/article_66df167c-d6bc-54be-b859-c0301658b2c6.html |archive-date=January 16, 2023 |access-date=January 28, 2023 |work=[[St. Louis Post-Dispatch]]}}</ref> The Mariners confirmed that they will replace the gray jerseys with the navy blue jerseys as their standard away uniforms for the 2023 season.<ref name="Mariners2023uniforms">{{Cite web |last=Creamer |first=Chris |date=January 27, 2023 |title=Seattle Mariners Drop Grey Unis for 2023, will wear Navy Blue for Road Games |url=https://news.sportslogos.net/2023/01/27/seattle-mariners-drop-grey-unis-for-2023-will-wear-navy-blue-for-road-games/baseball/ |archive-url=https://web.archive.org/web/20230128040431/https://news.sportslogos.net/2023/01/27/seattle-mariners-drop-grey-unis-for-2023-will-wear-navy-blue-for-road-games/baseball/ |archive-date=January 28, 2023 |access-date=January 28, 2023 |website=[[SportsLogos.net]]}}</ref><ref name="Mariners2023uniformsST">{{Cite news |last=Divish |first=Ryan |author-link=Ryan Divish |date=January 27, 2023 |title=Mariners ditching gray road jerseys because of new MLB rules |url=https://www.seattletimes.com/sports/mariners/mariners-ditching-gray-road-jerseys-because-of-new-mlb-rules/ |archive-url=https://web.archive.org/web/20230129020558/https://www.seattletimes.com/sports/mariners/mariners-ditching-gray-road-jerseys-because-of-new-mlb-rules/ |archive-date=January 29, 2023 |access-date=January 28, 2023 |work=[[Seattle Times]]}}</ref> The team will also stop using the powder blue jerseys during spring training.<ref name="Mariners2023uniforms" /> The choice to remove the gray and powder blue jerseys was based on feedback from players and fans, according to Kevin Martinez, the Mariners senior vice president of marketing and communications.<ref name="Mariners2023uniformsST" />

The Mariners criteria for retiring a uniform number is more selective than the standards for the Mariners Hall of Fame. To be eligible to have one's number retired, in addition to the criteria outlined for the Mariners' Hall of Fame, the former Mariners should have either:<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a) been elected to the National Baseball Hall of Fame and been in a Mariners uniform for at least five years, or <br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b) come close to such election and have spent substantially his entire career with the Mariners. <br />Eligibility shall not commence until after the former player has been voted on once for the National Baseball Hall of Fame, which for effectively means six years after retirement.<ref>{{Cite web |title=Mariners Hall of Fame Guidelines |url=http://seattle.mariners.mlb.com/sea/history/hof_guidelines.jsp |url-status=dead |archive-url=https://web.archive.org/web/20120123014625/http://seattle.mariners.mlb.com/sea/history/hof_guidelines.jsp |archive-date=January 23, 2012 |access-date=June 27, 2017 |publisher=Major League Baseball}}</ref>

==Culture==
==="Louie Louie"===
From the 1990 season through the 2021 season, as part of the seventh-inning stretch, after the crowd was led in singing "[[Take Me Out to the Ball Game]]" or "[[God Bless America]]" the public address system played [[the Kingsmen]]'s version of "[[Louie Louie]]". The song was a regional hit in the Northwest, covered by many local bands for nearly a decade until the [[Portland, Oregon|Portland]]-based Kingsmen recorded their version in 1963. In 1985, the song's regional importance was publicized by a campaign to make it the official state song of Washington. The tradition to play the song during the seventh inning stretch began as an attempt for the then new ownership group to put its stamp on the team, and was solidified on June 2, 1990, when the Kingsmen performed the song in the middle of the seventh inning live from atop a dugout. That game, [[Randy Johnson]] threw the first no-hitter in Mariners history.<ref>{{Cite news |last=Stone |first=Larry |date=April 19, 2021 |title=Here's why the Mariners aren't playing 'Louie Louie' during the seventh-inning stretch |url=https://www.seattletimes.com/sports/mariners/heres-why-the-mariners-arent-playing-louie-louie-during-the-seventh-inning-stretch/ |work=[[The Seattle Times]]}}</ref><ref>{{Cite web |last1=Mason |first1=Zach |last2=Leary |first2=Adrianne |date=April 18, 2022 |title=Oh, baby, "Louie Louie" did not have to go |url=https://www.lookoutlanding.com/2022/4/18/23029816/oh-baby-louie-louie-did-not-have-to-go-mariners-seventh-inning-stretch-macklemore-change |access-date=April 20, 2022 |website=Lookout Landing |publisher=SB Nation}}</ref>

For the 2022 season, the Mariners replaced "Louie Louie" with the [[Macklemore & Ryan Lewis]] song "[[Can't Hold Us]]". Replacing "Louie Louie" was a source of contention for some fans.<ref>{{Cite web |date=April 24, 2022 |title=Rant & Rave: What happened to 'Louie Louie' at Mariners games? |url=https://www.seattletimes.com/life/lifestyle/rant-rave-what-happened-to-louie-louie-at-mariners-games/ |website=[[The Seattle Times]]}}</ref> The Mariners stopped playing "Can't Hold Us" after Macklemore's comments at a Palestinian benefit concert in September 2024.<ref>{{Cite web |date=2024-09-27 |title=Mariners don't play Macklemore song after rapper's controversial remarks |url=https://www.seattletimes.com/sports/mariners/mariners-dont-play-macklemore-song-after-rappers-controversial-remarks/ |access-date=2025-03-06 |website=The Seattle Times |language=en-US}}</ref> 

'Louie Louie' returned to games in the 2025 season, remixed to a slightly more uptempo beat and interspersed with encouragement to the crowd ("Let's Go Mariners!").<ref>{{Cite web |date=2025-05-09 |title=How 'Louie Louie' returned to T-Mobile Park for 2025 Season |url=https://www.seattletimes.com/sports/mariners/how-louie-louie-returned-to-t-mobile-park-for-2025-mariners-season/ |access-date=2025-11-03 |website=The Seattle Times |language=en-US}}</ref>

===Buhner Buzz Cut Night===
In 1994, the Mariners started a promotion called "Buhner Buzz Cut Night". Inspired by [[Jay Buhner]]'s shaved head, any fan who was willing to have their head shaved before the game—or was already bald—would receive a free ticket to the game and a T-shirt with a slogan, such as "Bald Is Buhnerful" or "Take Me Out to the Bald Game". Hair 10 inches or longer was collected for charity. The promotion continued until Buhner's retirement in 2001, with a year's hiatus in 2000, and is still remembered by fans today. The club revived the promotion for its 30th anniversary in 2024, with Buhner giving catcher [[Cal Raleigh]] a buzz cut.<ref>{{Cite web |date=2024-06-14 |title=Cal Raleigh gets a trim as Mariners celebrate 30th anniversary of "Buhner Buzz Cut" night |url=https://apnews.com/article/mariners-raleigh-buzz-cut-2472bfc7d34881640715d78535af6a7f#:~:text=Seattle%20Mariners%20catcher%20Cal%20Raleigh,%20right,%20poses%20with%20former%20Mariners |access-date=2024-10-08 |website=AP News |language=en}}</ref>

===Rally Fries===
[[File:Rally fries sign.jpg|thumb|[[Boston Red Sox]] fans holding a sign requesting rally fries.]]
Rally Fries are a baseball [[tradition]] started by Mariners broadcaster [[Mike Blowers]] in 2007. During a game against the [[Cincinnati Reds]], a fan tried to catch a foul ball along the right-field line but in turn spilled his tray of [[french fries]] along the track. While chatting on the air and seeing the mishap, Blowers's partner, [[Dave Sims]], suggested that he should send a new tray of fries to the fan. Blowers agreed, and sent his intern to deliver a plate of fries to the man.<ref>{{Cite web |last=Hansen |first=Patrick |date=May 15, 2011 |title=Seattle Mariners: 5 Best Safeco Field Traditions |url=https://bleacherreport.com/articles/699195-seattle-mariners-5-best-safeco-field-traditions#/articles/699195-seattle-mariners-5-best-safeco-field-traditions |access-date=October 27, 2012 |website=[[Bleacher Report]]}}</ref>

At the Mariners' next game, fans made signs and boards asking Blowers for fries as well. Coincidentally, every time the fries were delivered, the Mariners seem to score or rally from a deficit, and thus the "Rally Fries" were created. This became so popular with the fans that signs were even seen when the Mariners were the visiting team, although on August 1, 2009, Blowers established that he only gives out fries at home games.<ref>{{Cite news |last=Moore |first=Jim |date=August 13, 2007 |title=Go 2 Guy: Fry, fry away -- rally fries take off |url=http://www.seattlepi.com/baseball/327493_moore14.html |work=Seattle Post-Intelligencer}}</ref>

Generally, Blowers would select a person or a group of people that appealed to him, whether it was through fans wearing elaborate costumes or waving funny signs and boards. The fries were usually delivered from [[Ivar's]], a Seattle-based seafood restaurant with a location at [[T-Mobile Park]]. The amount of fries given out varied with the size of the winning group of fans. The winners were generally selected around the 5th or 6th inning, although potential candidates were shown in almost every inning beforehand.

Sims confirmed in 2012 that the Rally Fries promotion had ended.<ref>{{Cite web |last=Sims |first=Dave |author-link=Dave Sims |date=Aug 21, 2012 |title=Dave Sims on Twitter |url=https://x.com/davesims_/status/237791753690824704 |website=Twitter |quote=It's time came and went!

Fans buying tickets to the JROD Squad section (referred to collectively as ''JROD's Squad'') receive a T-shirt showing a replica of a gold chain Rodríguez wears around his neck.<ref>{{Cite web |title=JROD's Squad {{!}} Seattle Mariners |url=https://www.mlb.com/mariners/tickets/specials/jrod-squad |access-date=October 7, 2023 |website=MLB.com |language=en}}</ref> Rodríguez often interacts with the JROD Squad, waving to them and throwing them balls at the end of innings.

=== Previous fan sections ===

====Area 51====
When [[Ichiro Suzuki]] played right field for the Mariners, seats in right field were often informally called Area 51, a nod to Suzuki's uniform number (51) and [[Area 51|the top-secret government site in Nevada of the same name]].<ref>{{Cite web |date=2008-03-28 |title=Mariners Outfielders: Welcome to Area 51 |url=https://www.heraldnet.com/sports/mariners-outfielders-welcome-to-area-51/ |access-date=2025-02-18 |website=Everett Herald |language=en-US}}</ref><ref>{{Cite web |last=Greenstein |first=Mike |date=2001-10-17 |title=The Book of Ichiro |url=https://www.wweek.com/portland/article-409-the-book-of-ichiro.html |access-date=2025-02-18 |website=Willamette Week |language=en}}</ref>

====King's Court====
As the 2011 season progressed, the Mariners' marketing staff came up with an idea to encourage the growing fanbase of star pitcher "King" [[Félix Hernández]]. Every Hernández start at T-Mobile Park was accompanied by the King's Court, a designated cheering section for fans to sing, chant, and cheer while donning yellow T-shirts and "K" cards supplied by the team. It was located in the lower seating area along the third baseline.<ref>{{Cite web |last=Kolloen |first=Seth |date=July 11, 2011 |title=The King's Court |url=https://grantland.com/features/the-king-court/ |access-date=2025-02-18 |website=Grantland |publisher=ESPN}}</ref> The team encouraged other activities, such as dressing like Larry Bernandez, Hernández's alter ego from a Mariners TV commercial, and awarding fans wearing costumes with a turkey leg.<ref>{{Cite web |last=Floyd |first=Brian |date=June 29, 2011 |title=Félix Hernández Ignites King's Court; Mariners, Marlins Play Calvinball |url=http://seattle.sbnation.com/seattle-mariners/2011/6/29/2246979/felix-hernandez-kings-court-mariners-marlins-calvinball |access-date=October 15, 2012 |website=[[SB Nation]]}}</ref>

The Supreme Court was a special event where the King's Court section was extended to the entirety of T-Mobile Park. The first Supreme Court was Hernández's first home game following his [[Félix Hernández's perfect game|perfect game]] in 2012.<ref>{{Cite web |date=2012-08-16 |title=Safeco Field hosts first ever Supreme Court in honor of Felix's perfect game |url=https://www.mlb.com/news/safeco-hosts-first-supreme-court-in-honor-of-felixs-perfect-game/c-36813588 |access-date=2025-02-18 |website=MLB.com |language=en}}</ref> Following opening day 2012, it occurred each year at Hernández's first home game of each season.

The King's Court ended following Hernández's departure from the Mariners at the end of the 2019 season.<ref>{{Cite web |date=2019-09-27 |title=Mariners' Felix Hernandez shows appreciation for 'King's Court' fan section during likely final start with Seattle |url=https://www.cbssports.com/mlb/news/mariners-felix-hernandez-shows-appreciation-for-kings-court-fan-section-during-likely-final-start-with-seattle/ |access-date=2025-02-18 |website=CBSSports.com |language=en}}</ref>

====Maple Grove====
During the 2017 season, fans created the Maple Grove, a celebration of Canadian pitcher [[James Paxton (baseball)|James Paxton]] and inspired by the King's Court. At home games where Paxton started, a group of fans sat under a Maple Grove banner, typically in the left-field bleachers. A potted maple tree was also present in their section, provided by the Mariners. The Grove dubbed the tree "Stick Rizzs", referencing long-time broadcaster [[Rick Rizzs]].<ref name=":1">{{Cite news |last=Moore |first=Jim |title=Fan-planted 'Maple Grove' grows at Safeco Field |url=https://www.seattlepi.com/sports/moore/article/Jim-Moore-Fan-planted-Maple-Grove-James-Paxton-11747597.php |url-status=dead |archive-url=https://web.archive.org/web/20170810170536/https://www.seattlepi.com/sports/moore/article/Jim-Moore-Fan-planted-Maple-Grove-James-Paxton-11747597.php |archive-date=2017-08-10 |work=Seattle P-I}}</ref><ref>{{Cite web |date=2017-07-25 |title=The Mariners put a maple tree in the stands to celebrate James 'Big Maple' Paxton's start |url=https://www.mlb.com/cut4/mariners-put-a-maple-tree-in-the-stands-for-james-paxton-c244268084 |access-date=2025-02-18 |website=MLB.com |language=en}}</ref>

When Paxton got to two strikes on a batter, the Grove held up "Eh" Cards, a tip of the cap to Paxton's home country of Canada and a nod to the "K" (for strikeout) cards held up in King's Court.<ref name=":1" /> Variant cards have also been produced for special occasions, such as when a planned Paxton start turned into a Hernández start (a King's Grove, with "K'eh" cards to cheer for Hernández). Other special cards celebrated Paxton reaching 300 strikeouts, and a tribute to broadcaster [[Angie Mentink]] ("A" cards, to show support after she had publicly disclosed her breast cancer diagnosis). An "Eh" card is now part of the [[National Baseball Hall of Fame and Museum|Baseball Hall of Fame]]'s collection.<ref>{{Cite web |title=EH sign; in support for Canadian pitcher James Paxton, 2018 {{!}} ArchivesSpace Public Interface |url=https://archives.baseballhall.org/repositories/2/archival_objects/75534 |access-date=2025-01-10 |website=archives.baseballhall.org}}</ref>

The Maple Grove differed from the King's Court in that it was created and organized by fans, while the Court was promoted by the Mariners' marketing team. When asked, Paxton stated that fans creating the Maple Grove was really special to him and that he never imagined that something of the sort would ever be done for him.<ref>{{Cite web |last=Giambalvo |first=Emily |date=July 27, 2017 |title=Mariners fans created the 'Maple Grove' for Canadian James Paxton, and he loves it |url=https://www.seattletimes.com/sports/mariners/mariners-fans-created-the-maple-grove-for-canadian-james-paxton-and-he-loves-it/ |access-date=January 19, 2020 |newspaper=[[The Seattle Times]]}}</ref> The Grove continued until Paxton was traded to the Yankees following the 2018 season.<ref>{{Cite web |last=Divish |first=Ryan |author-link=Ryan Divish |date=November 19, 2018 |title=Mariners trade left-hander James Paxton to the Yankees for three prospects |url=https://www.seattletimes.com/sports/mariners/mariners-trade-james-paxton-to-the-yankees-for-three-prospects/ |access-date=January 31, 2019 |website=The Seattle Times |language=en-US}}</ref>

==Rivalries==
=== Divisional ===
The Mariners also held a longstanding divisional rivalry with the [[Oakland Athletics]] as they would often battle for playoff contention or lead of the division through the early 2000s. Following the realignment of the division in 2013, the Mariners have also built a recent rivalry with the [[Houston Astros]] as both teams have handily fought for control of the division.<ref>{{Cite web |title=Why Houston Astros Joining AL West Helps the Seattle Mariners |url=https://bleacherreport.com/articles/963588-why-houston-astros-joining-al-west-helps-the-seattle-mariners |website=[[Bleacher Report]]}}</ref><ref>{{Cite web |last=Preusser |first=Kate |date=July 21, 2022 |title=A Mariners-Astros rivalry is the best thing for baseball today |url=https://www.lookoutlanding.com/2022/7/21/23272373/mariners-astros-rivalry-sell-some-tickets-rob-manfred |access-date=June 4, 2023 |website=Lookout Landing |publisher=Vox Media}}</ref>

====Los Angeles Angels====
The [[Los Angeles Angels]] have maintained an off-and-on rivalry with the Mariners as both teams have often fought for control of the division or a playoff berth. Both teams often clashed for playoff positions during the early 2000s as the Mariners boasted a 116 win team in 2001 while the Angels managed to win the [[2002 World Series|World Series]] in 2002. Despite both teams encountering a decline through the decade, regular matchups often developed into clashes for relevance in the division. Recently, both teams were each trying to end postseason droughts, bolstered by players such as [[Julio Rodríguez]] and [[Ty France]] for Seattle and [[Shohei Ohtani]] and [[Mike Trout]] for the Angels<ref>{{Cite web |title=Seattle Mariners Tailgating |url=https://supertailgate.com/stadium/seattle-mariners |website=Supertailgate.com |access-date=April 6, 2023 |archive-date=April 8, 2023 |archive-url=https://web.archive.org/web/20230408230447/https://supertailgate.com/stadium/seattle-mariners |url-status=dead }}</ref><ref>{{Cite web |last=Stone |first=Larry |date=August 26, 2007 |title=Rivalry renewal |url=https://www.spokesman.com/stories/2007/aug/26/rivalry-renewal/ |website=Spokesman.com |publisher=Seattle Times}}</ref> The two teams have met 741 times, with the Angels leading the series 400–341.

====Houston Astros====
The Mariners and [[Houston Astros]] have fought for control of the division in recent years, since the Mariners started periodically contending for the postseason in 2014. The Astros lead the all-time regular season series 132–97 and have a perfect 3–0 record against Seattle in the postseason.<ref>{{Cite web |title=Houston Astros vs. Seattle Mariners: Head-to-Head Reg Season and Playoffs Stats Comparison |url=https://www.sports-reference.com/stathead/baseball/vs/houston-astros-vs-seattle-mariners |access-date=2025-11-03 |website=Stathead}}</ref> 

The 2022 season saw the Mariners return to the playoffs, in a year that included multiple bench-clearing incidents between the Astros and Mariners during the regular season.<ref>{{Cite web |date=2023-09-28 |title=Hector Neris apology does little to warm over Julio Rodriguez |url=https://www.espn.com/mlb/story/_/id/38514750/astros-hector-neris-apologizes-julio-rodriguez-mariners |access-date=2025-02-18 |website=ESPN}}</ref><ref>{{Cite web |date=2024-09-25 |title=Julio Rodriguez homers off Astros' Hector Neris to reach 20-20 club again |url=https://www.seattletimes.com/sports/mariners/julio-rodriguez-homers-off-astros-hector-neris-to-reach-20-20-club-again-mariners-notebook/ |access-date=2025-02-18 |website=The Seattle Times}}</ref> The Mariners and Astros faced off in the 2022 ALDS, with Houston sweeping the Mariners in 3 games. The third and final game of that series was among the longest in postseason history; its 18 innings matched the longest game in playoff history and its 6 hours, 22 minutes was the third-longest in time.<ref>{{Cite web |date=2022-10-15 |title='Pena's 18th-inning HR sends Astros past Mariners for sweep |url=https://www.espn.com/mlb/recap/_/gameId/401467563}}</ref>

The rivalry was a brief focus at the end of the 2025 season, after a 3 game sweep of the Astros in Houston by the Mariners in late September.<ref>{{Cite web |date=2025-09-21 |title='This is crunch time': Astros' playoff hopes dwindle after Mariners' sweep |url=https://www.mlb.com/news/astros-swept-by-mariners-in-blow-to-postseason-hunt}}</ref> The sweep put the Mariners 3 games up in the division with 6 to play while all but eliminating the Astros from postseason contention. 3 days later, the Mariners won the AL West Division championship for the first time in 24 years.

=== American League ===

=== Toronto Blue Jays ===
Although the Seattle Mariners and [[Toronto Blue Jays]] are not a divisional rival, many Blue Jays fans from Western Canada travel to Seattle when the Blue Jays are the visiting team. Seattle is about a three-hour drive from Vancouver. ''[[The Seattle Times]]'' estimated that Blue Jays fans represented around 70 percent of the crowd in [[T-Mobile Park|Safeco Field]] for a June 2017 weekend series.<ref>{{cite web |last=Feng |first=Minnia |date=June 12, 2017 |title=What Safeco Field is Like when It Gets Invaded by Blue Jays Fans |url=https://www.vice.com/en/article/what-safeco-field-is-like-when-it-gets-invaded-by-blue-jays-fans/ |website=vice.com |location=United States |publisher=Vice |access-date=October 27, 2025}}</ref> Additionally, both teams joined the league at the same time in the [[1977 Major League Baseball expansion]]. The Mariners broke their playoff drought in Toronto in the [[2022 American League Wild Card Series]] with a dramatic comeback in Game Two, after being down by a deficit of one run to eight, winning by a final score of ten to nine. The two teams faced off again in the post-season in the [[2025 American League Championship Series]]. Seattle took the first two games on the road in Toronto, but ultimately lost the series three games to four, with the Blue Jays winning game seven at home.<ref>{{Cite web |last=Hoch |first=Bryan |title=By George, Blue Jays reach first World Series since 1993! |url=https://www.mlb.com/news/blue-jays-win-2025-alcs |access-date=2026-02-03 |website=MLB.com |language=en}}</ref>

===Interleague===
====The Vedder Cup====
An unusual rivalry exists between the Mariners and the [[National League (baseball)|National League]]'s [[San Diego Padres]].<ref>{{Cite web |title=Western Front: A Brief History of the Vedder Cup |work=Baseball Prospectus |date=June 12, 2012 |url=https://www.baseballprospectus.com/news/article/17243/western-front-a-brief-history-of-the-vedder-cup/}}</ref> The matchup was designated one of the 15 "naturalized rivalries" when interleague play began in 1997, and the teams have played every year since, except 2017.<ref>{{Cite web |last=Togerson |first=Derek |date=2016-05-30 |title=How the Vedder Cup Came to Be |url=https://www.nbcsandiego.com/news/local/how-the-vedder-cup-came-to-be/60870/ |website=NBC San Diego}}</ref><ref>{{Cite web |date=2013-03-14 |title=Mariners "Heating Up" the Rivalry |url=https://www.gaslampball.com/2013/3/14/4104230/mariners-heating-up-the-rivalry |website=Gaslamp Ball |publisher=SB Nation}}</ref> 

Little on the surface links the two teams to any actual hostility, as both play in separate leagues and in cities that sit about 1,250 miles apart. Still, they share a spring training facility—the [[Peoria Sports Complex]] in [[Peoria, Arizona]]<ref>{{Cite web |title=Power Ranking Every 'Hometown' Interleague Rivalry |url=https://bleacherreport.com/articles/1652895-power-ranking-every-hometown-interleague-rivalry |website=[[Bleacher Report]]}}</ref>—and in many years have competed for draft picks and prospects after failing to make the playoffs.
