Here’s a look at the Mariners’ 2025 schedule

The Seattle Mariners will have a front-loaded home schedule in 2025, with 18 of their first 30 games to be played at T-Mobile Park, the club announced Thursday as part of its schedule release.

The Mariners will open 2025 at home against the A’s on Thursday, March 27, followed by a three-game home series against the Detroit Tigers from March 31-April 2.

The Mariners play a series at San Francisco, April 4-6, before returning home for another homestand against the Astros and Rangers.

The 2025 season will be the third under MLB’s Interleague Balanced Schedule format.

In a slight tweak to the format for 2025, the Mariners will play 13 games vs. the four other AL West teams (Astros, Angels, A’s and Rangers); either six or seven games (one road series/one home series) vs. AL Central and AL East teams; three games (one series, either home or road) vs. 14 National League opponents; plus six games (three at home, three on the road) vs. their “natural rival,” the San Diego Padres.

In May, the Mariners will make their first trip to Sacramento in the A’s first season away from Oakland. The A’s announced earlier that they plan to play home games at Sacramento’s Sutter Health Park — home of the Triple-A River Cats — as they continue to try to relocate to Las Vegas in 2028.

The Mariners have two road trips that feature 10 games in 10 days:

— May 16-15 in San Diego, Chicago (White Sox) and Houston.
— June 20-29 in Chicago (Cubs), Minnesota and Texas.

The Mariners have four 2025 trips scheduled to the Eastern time zone:

— April 15-24 in Cincinnati, Toronto and Boston.
— July 8-13 in New York (Yankees) and Detroit.
— Aug. 12-20 in Baltimore, New York (Mets) and Philadelphia (nine games in nine days).
— Aug. 29-Sept. 7 in Cleveland, Tampa Bay and Atlanta (nine games in 10 days).

In a break from tradition, the Mariners will not play AL West opponents to close out the season in 2025. Instead, the Rockies and Dodgers come to Seattle for two late-September series.
