Seattle Mariners Should Target These 5 Free Agent Hitters
The Seattle Mariners are poised for a significant offseason as they look to enhance their roster in pursuit of a playoff berth. With MLB free agency set to commence, the Mariners are evaluating potential free agent hitters to address their needs. Here are five hitters that Seattle should consider targeting.
1. Kyle Tucker, OF
Kyle Tucker is predicted to be one of the most sought-after free agents. At 28, he boasts an impressive .895 OPS and a remarkable 152 wRC+ over the past two seasons. Despite missing three months in 2024 due to a fractured shin, Tucker recorded an 8.7 fWAR during this time, the highest among all free agent position players. However, signing him will come at a significant price, with projections suggesting a lengthy contract averaging 10.1 years at around $391.5 million.
2. Alex Bregman, 3B
Alex Bregman fits the Mariners perfectly on paper. Known for his strong batting skills and excellent defense, he recorded a 125 wRC+ and a 3.6 fWAR over 114 games in 2024. His leadership qualities and playoff experience make him a valuable asset. Bregman has opted out of his previous contract, which could lead to a new deal estimated at six years for $180 million, extending into his late 30s.
3. Ryan O’Hearn, 1B
Ryan O’Hearn could serve as a viable alternative at first base if Josh Naylor does not return. The 32-year-old first-time All-Star had a stellar season, with a career-best 127 wRC+ and 3.0 fWAR. While concerns exist regarding his ability to perform consistently against left-handed pitchers, he has made progress, posting a career-high .832 OPS against them in 2025. O’Hearn is projected to secure a three-year deal worth $45 million.
4. Willi Castro, UTL
Positional versatility is Willi Castro’s standout feature. Although his offensive statistics are modest—never exceeding a 107 wRC+—he has demonstrated flexibility by playing multiple positions throughout his seven-year career. His tactical strength may benefit the Mariners, especially with promising prospects on the rise. Castro’s expected contract is two years at $22 million.
5. Munetaka Murakami, 3B/1B
While not officially a free agent yet, Munetaka Murakami is anticipated to enter the market after being posted by the Yakult Swallows. The 25-year-old became the youngest Triple Crown winner in NPB history in 2022. Despite injuries and a substantial strikeout rate of 28.8% over the last three years, he continues to attract attention for his power, hitting 22 homers in just 56 games last season. A seven-year deal projected at $140 million could set a record for a Japanese player in MLB.
Conclusion
The Seattle Mariners have a critical offseason ahead. Targeting these free agent hitters could bolster their lineup and enhance their chances of returning to the postseason. With significant investments potentially on the horizon, the Mariners could reshape their roster dramatically.
