Seatle Mariners 2025 schedule, players and season preview
📊 Current season snapshot
The Mariners are off to a scorching start in 2025, sitting atop the AL West with a 20–14 record. Despite ranking middle-of-the-pack in team batting average (.244, 14th in MLB), they’ve been efficient at generating runs (174, 8th in MLB), while the pitching staff has posted a solid 3.74 ERA (12th).
Recent injuries to outfielders Mitch Haniger and Luke Raley (right oblique strain) have tested the team’s depth, but strong performances from Randy Arozarena and Cal Raleigh have kept the offense productive.
🏟️ T-Mobile momentum
The 2025 Mariners opened their season with a slow 4–8 start, including being swept by the San Francisco Giants, but an 8th-inning grand slam by Randy Arozarena on April 9 sparked a turnaround that has seen them win seven straight series to climb to the top of the division standings.
With plenty of home games to start the season, the team has taken full advantage of the T-Mobile Park crowd. The signing of Cal Raleigh to a six-year, $105 million extension just before the season has given fans additional reason for optimism.

🌱 Farm system focus: baseball’s best prospect pipeline
| Name | Position | ETA | What to expect |
|---|---|---|---|
| Colt Emerson | SS/3B | Late 2025 | Dynamic lefty hitter with advanced plate discipline |
| Cole Young | SS | Mid 2025 | Polished bat who could claim the 2B job this season |
| Felnin Celesten | SS | 2027 | Five-tool potential with plus speed and power projection |
| Harry Ford | C | Late 2025 | Athletic backstop who gives back to the community |
| Jurrangelo Cijntje | RHP | 2026 | Unique switch-pitcher who throws with both arms |
The Mariners’ farm system is ranked among baseball’s best, with exceptional depth that extends well beyond their top prospects. Emerson and Young could both reach Seattle this season, potentially adding immediate impact to a lineup that has been searching for consistent production.
⚾ Rotation excellence continues
Seattle’s pitching development has become the envy of baseball, with homegrown stars like Logan Gilbert and George Kirby anchoring one of the game’s best rotations. The bullpen has been equally impressive, with closer Andrés Muñoz tying for the MLB lead with 11 saves in April without allowing a single run.
The pitching staff has faced early challenges, with several key arms starting the season on the injured list, including Kirby, Matt Brash, and Troy Taylor. However, depth has prevailed with rookies like Logan Evans making successful MLB debuts.
🎯 Three keys to October baseball
- Health in the lineup – Keeping key contributors on the field has been a challenge early in the season
- Prospect integration – Finding the right time to promote top prospects like Cole Young and Colt Emerson
- Divisional success – Beating AL West rivals, especially defending champion Houston, will be critical

🏁 Road ahead
The Mariners will close the 2025 regular season with a six-game homestand, facing the Colorado Rockies (September 23–25) and Los Angeles Dodgers (September 26–28). For fans in Northern California, the team makes two trips to Sacramento to face the Athletics on May 5–7 and July 28–30 at Sutter Health Park.
With Jerry Dipoto entering his tenth season in the front office and pressure mounting to reach the postseason, this could be the year Seattle finally breaks through after missing the playoffs in 22 of the past 23 seasons.
