Seattle Mariners

{{Main|History of the Seattle Mariners}}

The Mariners were created as a result of a lawsuit. In {{mlby|1970}}, after Bud Selig bought the Seattle Pilots and moved them to Milwaukee to become the Milwaukee Brewers, the city of Seattle, King County, and the state of Washington (represented by then-state Attorney General and future U.S. Senator Slade Gorton) sued the American League for breach of contract.{{Cite news |last=Cour |first=Jim |date=June 27, 1999 |title=No Love Lost for Kingdome |url=https://www.latimes.com/archives/la-xpm-1999-jun-27-sp-50611-story.html |access-date=January 18, 2020 |work=Los Angeles Times |agency=Associated Press}} Confident that Major League Baseball would return to Seattle within a few years, King County built the multi-purpose Kingdome, which would become home to the National Football League's expansion Seattle Seahawks in 1976.{{Cite web |last=MacIntosh |first=Heather |date=March 1, 2000 |title=Kingdome: The Controversial Birth of a Seattle Icon (1959–1976) |url=http://www.historylink.org/index.cfm?DisplayPage=output.cfm&file_id=2164 |access-date=March 15, 2011 |publisher=HistoryLink}} The name "Mariners" was chosen by club officials in August 1976 from more than 600 names submitted by 15,000 entrants in a "name the team" contest.

That year, pitcher Diego Seguí, in his last major league season, became the only player to play for both the Pilots and the Mariners. The Mariners finished with a 64–98 record, matching the 1969 Pilots' record. The team avoided finishing in last place in the AL West by half a game. The Mariners would not post a winning record or finish above 4th place in any of their first 14 seasons. In 1979, Seattle hosted the 50th Major League Baseball All-Star Game.

(Piniella was selected by the Pilots in the 1968 expansion draft but did not play for Seattle, being traded in April 1969 to the Kansas City Royals, where he earned AL Rookie of the Year honors that year.)

The Mariners had a 93-win season in {{mlby|2002}} but failed to make the postseason. Manager Lou Piniella was traded to the Tampa Bay Rays during the offseason. The team repeated with 93 wins in 2003 and also did not qualify for the playoffs.

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 season, the organization pivoted to a rebuild, trading several players for prospects. Following a fallow period of 2019–20, the team returned to contention in 2021, winning 90 games but falling short of the playoffs. In 2022, with a new core including Julio Rodríguez, J. P.

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.

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 in the uniform design from 1987 to 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."

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

The Mariners did not wear green uniforms from 1997 to 2010, after which it became a regular part of their uniform rotation.

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. This cream-colored "fauxback" uniform features the current logo and lettering style in a royal blue and gold color scheme, a throwback to the original team colors. Unlike the rest of the uniform set, the back of the jersey does not display the player name.{{Cite web |last=Lewis |first=Adam |date=January 23, 2015 |title=Mariners Unveil New Alternate Home Uniforms |url=http://sportspressnw.com/2197039/2015/mariners-unveil-new-alternate-home-uniforms |access-date=January 31, 2015 |website=Sports Press NW}} The cap features the current cap logo in the throwback colors.{{Cite news |last=Divish |first=Ryan |author-link=Ryan Divish |date=January 23, 2015 |title=Mariners debut new alternate uniform for Sunday home games |url=http://blogs.seattletimes.com/mariners/2015/01/23/mariners-debut-new-home-alternate-uniform-for-sunday-games/ |url-status=dead |archive-url=https://web.archive.org/web/20150201001615/http://blogs.seattletimes.com/mariners/2015/01/23/mariners-debut-new-home-alternate-uniform-for-sunday-games/ |archive-date=February 1, 2015 |access-date=January 31, 2015 |work=The Seattle Times}}

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 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."{{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}} The Mariners confirmed that they will replace the gray jerseys with the navy blue jerseys as their standard away uniforms for the 2023 season.{{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}}{{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}} The team will also stop using the powder blue jerseys during spring training. 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.

The Mariners' City Connect uniform is a visual nod to Seattle's baseball history. The jersey includes a sleeve patch featuring Mount Rainier and the letters "PNW," an acronym for Pacific Northwest. The jersey also includes the inaugural colors of the team and the word "Seattle" across the chest lettering reminiscent of the Seattle Pilots. The jersey is paired with a cap that has new design of the trident logo and black pants. This uniform is primarily worn during Friday home games.{{Cite web |title=Spirit, colors of Pacific Northwest come alive in Mariners' City Connect unis |url=https://www.mlb.com/news/mariners-city-connect-uniforms-unveiled |access-date=April 28, 2023 |website=MLB.com |language=en}} The team wore the City Connect uniform more frequently in 2024, since they won most of their games in the alternates.{{Cite web |date=2024-09-15 |title=Seattle Mariners Wearing Fan-Favorite Threads for Series Final Against Texas Rangers |url=https://www.si.com/mlb/mariners/news/seattle-mariners-will-wear-fan-favorite-and-lucky-citty-connect-uniforms-for-series-finale-against-texas-rangers-on-sunday |access-date=2025-03-06 |website=Seattle Mariners On SI |language=en-US}} In the upcoming 2025 season, the Mariners will once again partner with Nintendo of America, with the Nintendo “racetrack” logo on the sleeve of the home game jersey and the logo of the Nintendo Switch 2 on the sleeve of the away game jersey.{{Cite web |date=2025-03-20 |title=The Seattle Mariners are getting Nintendo patches on their jerseys |url=https://www.espn.com/gaming/story/_/id/44330467/seattle-mariners-nintendo-jerseys |access-date=2025-03-20 |website=ESPN.com |language=en}}

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:
      a) been elected to the National Baseball Hall of Fame and been in a Mariners uniform for at least five years, or
      b) come close to such election and have spent substantially his entire career with the Mariners.
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.{{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}}

Martínez played his entire career with the Mariners and first appeared on the Hall of Fame ballot in {{bhofy|2010}}.

Randy Johnson will also have his No. 51 retired by the Mariners in 2026. Johnson played 10 seasons with the Mariners, from 1989 until mid-1998, and was elected to the Hall of Fame in 2015. The #51 was withheld until 2001, when it was issued to Ichiro Suzuki upon his request. No other player, besides Suzuki, has worn that number for the Mariners since Johnson. On June 2, 2025, the Mariners announced they will also retire 51 in honor of Johnson in 2026, however the date has yet to be released, and is set to be released once the schedule for the 2026 season is finalized. {{Cite web |title=Mariners to Retire Randy Johnson's #51 During 2026 Season |url=https://www.mlb.com/press-release/mariners-to-retire-randy-johnson-s-51-during-2026-season |access-date=2025-06-02 |website=MLB.com |language=en}}

Currently, one other player has definitively met the requirements to have their number retired but not yet had the team retire or announce its plans to retire their numbers, Adrián Beltré.

Beltré, a Mariner for five seasons (2005–2009), was elected to the Hall of Fame in 2024. He wore number 5 in 2005, then number 29 during his last four years in Seattle. Both numbers have been reissued several times since Beltré left Seattle, with Cal Raleigh currently wearing number 29 and Cade Marlowe most recently wearing number 5.{{Cite web |title=2025 Seattle Mariners Roster (40-man) |url=https://www.baseball-reference.com/teams/SEA/2025-roster.shtml |website=Baseball-Reference.com}} The Mariners have not indicated any plans to retire Beltré's number.

Lou Piniella's number 14 was not given to any uniformed personnel after his 2002 departure until it was issued to third base coach Manny Acta in 2016.

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-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.{{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}}{{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}}

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.{{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}}

File:Rally fries sign.jpg 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.{{Cite web |last=Hansen |first=Patrick |date=May 15, 2011 |title=Seattle Mariners: 5 Best Safeco Field Traditions |url=http://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}}

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.{{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}}

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.{{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!

The JROD Squad honors Mariners center fielder Julio Rodríguez. The location varies, although it is usually in seats in center field. 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.{{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}} Rodríguez often interacts with the JROD Squad, waving to them and throwing them balls at the end of innings.

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 the top-secret government site in Nevada of the same name.{{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}}{{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}}

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.

The first Supreme Court was Hernández's first home game following his perfect game in 2012.{{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}} Following opening day 2012, it occurred each year at Hernández's first home game of each season.

During the 2017 season, fans created the Maple Grove, a celebration of Canadian pitcher 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.{{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}}{{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}}

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. 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 Baseball Hall of Fame's collection.{{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}}

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.{{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}} The Grove continued until Paxton was traded to the Yankees following the 2018 season.{{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}}

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.{{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}}{{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}}

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 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{{Cite web |title=Seattle Mariners Tailgating |url=https://supertailgate.com/stadium/seattle-mariners |website=Supertailgate.com}}{{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}} The two teams have met 741 times, with the Angels leading the series 400–341.
