The 2026 Seattle Mariners season is the 50th season in franchise history and their 27th full season (28th overall) at T-Mobile Park, their home ballpark in Seattle, Washington. The Mariners lost on Opening Day on March 26 against the Cleveland Guardians in Seattle. The regular season will end on September 27 against the Los Angeles Angels at home. The team is looking to improve their performance from their previous season, where they reached the 2025 American League Championship Series.
The Mariners plan to retire Randy Johnson's uniform number 51 on May 2. The team retired the number in 2025 for Ichiro Suzuki. [1] [2] The Mariners are wearing a uniform patch commemorating their 50th season. [3]
Coming off an AL West division title and American League Championship Series appearance, the Mariners acted early in the offseason, re-signing first baseman Josh Naylor, who had been a 2025 mid-season pickup, to a five-year contract in mid-November 2025. [4]
On December 5, the Mariners announced their coaching staff for 2026. Two former coaches left for bench coach jobs, with third base coach Kristopher Negrón joining the Pittsburgh Pirates and bullpen coach Tony Arnerich going to the Cleveland Guardians. Carlos Cardoza, previously the Frisco RoughRiders manager, was named the third base coach, and former Mariner catcher Austin Nola began his coaching career as the bullpen coach. Jake McKinley, formerly the Nevada Wolf Pack coach, was named the field coordinator, replacing Louis Boyd, who took another role with the Mariners. Seattle retained all other coaches from 2025. [5] [6]
The Mariners made two trades to fill areas of need and send out prospects, acquiring reliever José A. Ferrer from the Washington Nationals for catcher Harry Ford [7] and getting utility player Brendan Donovan from the St. Louis Cardinals for four minor leaguers and a draft pick. [8] The Donovan trade was finalized thanks in part to two former Mariners and FanGraphs bloggers, with Dave Cameron, Seattle's senior director of player personnel, reaching out to Jeff Sullivan, a senior analyst with the Tampa Bay Rays, to include the Rays in a three-way trade. [9]
The Mariners made smaller signings to fill smaller roles, signing Rob Refsnyder as a right-handed bat to face lefties [10] and signing Andrew Knizner and Mitch Garver for the backup catcher job. [11] [12] Garver won the role, with Knizner electing free agency. [13]
Pitcher Logan Evans had Tommy John surgery in January 2026, with an expected 12-month recovery. [14]
In January, the team announced that they would wear Seattle Steelheads-inspired uniforms in Sunday home games, replacing their cream alternates. [15]
Longtime broadcaster Rick Rizzs announced in January that he would retire after the season. [16] Fellow broadcaster Angine Mentink suffered a stroke in February. [17]
Pitchers and catchers reported to the Mariners' spring training facility, the Peoria Sports Complex, between February 9 and 11, with the first spring training game held on February 20, against the San Diego Padres, who also train in Peoria, Arizona. [29]
The Mariners non-roster invitees to spring training included top prospects, such as Colt Emerson, Ryan Sloan, and Kade Anderson; former major leaguers on minor league contracts Dane Dunning, Patrick Wisdom, and Randy Dobnak; and returning organizational players including Casey Lawrence, Austin Kitchen, and Guillo Zuñiga. [30]
Pitcher Bryce Miller and shortstop J. P. Crawford dealt with injuries in late February. [31] [32] Both players began the season on the injured list, along with utility player Miles Mastrobuoni. [33]
The Mariners had 16 players selected to play in the 2026 World Baseball Classic (WBC), held during spring training, including six minor leaguers. Outfielders Julio Rodríguez and Randy Arozarena returned to the Dominican Republic and Mexico, respectively, with All-Star closer Andrés Muñoz also playing for Mexico. Prior to the WBC rosters being announced in February, [34] both Cal Raleigh and Gabe Speier committed to the United States. [35] Josh Naylor was the captain for Canada, after previously playing in the 2017 WBC. [36] Reliever Eduard Bazardo joined Venezuela. Part-time players Dominic Canzone and Miles Mastrobuoni joined Italy. South Korea selected minor league signee Dane Dunning, while prospect Michael Arroyo and reliever Guillo Zuñiga joined Colombia, and four other minor league pitchers were chosen by other national teams. [34] Mastrobuoni suffered a calf injury during pool play and returned to Mariners spring training. [37]
During a U.S.–Mexico game on March 10, Arozarena, ahead of his first plate appearance, attempted to shake Raleigh's hand, which Raleigh declined. [38] Naylor made a similar attempt when Canada faced the U.S., though Naylor said after the game that he was joking with Raleigh. [39] Raleigh, who was hitless in the WBC, was benched in the final two games, including facing Rodriguez and the Dominican Republic. [40]

Updated with the results of all games through April 12, 2026.
The Mariners lost on Opening Day and split their opening four-game series at home with the Cleveland Guardians, with Emerson Hancock getting a career-high nine strikeouts to salvage the series. [41] [42] After Cal Raleigh's walk-off single, the Mariners lost the final two games of their series against the New York Yankees. [43] [44] Following the opening homestand, the team signed top prospect shortstop Colt Emerson to an eight-year, $95 million contract extension, though he remained in the minors. [45] Incumbent shortstop J. P. Crawford came off the injured list. [46]
Seattle offensive struggles continued on their first road trip. [47] After defeating the Los Angeles Angels on April 3, the team lost five game in a row.

[49] During the road trip, outfielder Víctor Robles went on the injured list, replaced by Connor Joe, who made a costly fielding error and was hitless in his Mariners debut. [50] [51]
The Mariners ended their losing streak by winning two games against the Houston Astros, scoring at least 8 runs in each game. [52] Prior to the first game, the Mariners unveiled a statue of Ichiro Suzuki, with the statue's bat breaking during the ceremony. [53] In the second game, Crawford tied a franchise record with his eighth walk-off hit. [52]
