MLB Free Agent Rankings: Top Five First Basemen for 2025
As the 2025 MLB offseason approaches, teams are gearing up to make strategic moves to bolster their rosters. While the Boston Red Sox may not have an immediate need at first base, with Triston Casas firmly positioned as their Opening Day starter, the front office might still explore the free-agent market for a right-handed slugger to enhance their lineup. Here’s a look at the top five first basemen set to hit free agency, with a focus on their potential impact and fit for the Red Sox.
1. Pete Alonso
Age: 30
2024 Stats: .240/.329/.459, 34 HR, 88 RBI, 172 SO, 70 BB (162 games)
Pete Alonso, the New York Mets’ star first baseman, is a name that commands attention. In 2024, he showcased his durability by playing all 162 games, a feat that speaks volumes about his fitness and commitment. Known for his power, Alonso has consistently hit at least 34 home runs in every full season, except for the shortened 2020 campaign. His ability to deliver in clutch moments, particularly during the postseason, could make him a prime target for teams looking to add firepower.
For the Red Sox, Alonso’s swing is tailor-made for Fenway Park, where the Green Monster could serve as an additional advantage for his left-handed bat. If the Mets decide to move on from their All-Star slugger, Boston should seriously consider bringing him on board as a designated hitter/first baseman.
2. Christian Walker
Age: 34
2024 Stats: .251/.335/.468, 26 HR, 84 RBI, 133 SO, 55 BB (130 games)
Christian Walker has quietly established himself as one of the most underrated players in baseball. His defensive prowess at first base is underscored by two Gold Gloves, and he has proven to be a reliable source of power, averaging around 30 home runs when healthy. After spending eight seasons with the Arizona Diamondbacks, Walker is likely to attract significant interest on the open market.
While the D’backs will undoubtedly make an effort to retain him, Walker’s combination of offensive and defensive skills could be a valuable asset for the Red Sox, especially if they seek to improve their overall team defense while adding some right-handed power.
3. Paul Goldschmidt
Age: 37
2024 Stats: .245/.302/.414, 22 HR, 65 RBI, 173 SO, 47 BB
Paul Goldschmidt, a former NL MVP, had a challenging 2024 season, posting the lowest offensive numbers of his illustrious career. Despite this downturn, his track record speaks for itself, and he remains a formidable presence at the plate. With a history of consistent performance, Goldschmidt could be a bounce-back candidate for teams willing to take a chance on his veteran experience.
For the Red Sox, adding Goldschmidt could provide a stabilizing influence in the lineup, particularly if they are looking for a player who can mentor younger talent while still contributing at a high level. However, teams will need to weigh his recent performance against his potential for resurgence.
4. Anthony Rizzo
Age: 35
2024 Stats: .228/.301/.335, 8 HR, 35 RBI, 65 SO, 27 BB (92 games)
Anthony Rizzo’s 2024 season was marred by injury, as he spent a significant portion of the year on the injured list due to a broken arm. When he was on the field, his performance was lackluster, marking his worst offensive output since his rookie year. However, Rizzo’s resume is impressive, featuring three All-Star selections, a World Series title, and four Gold Gloves.
The New York Yankees hold a $17 million club option for Rizzo in 2025, but if they decline it, he could be a valuable addition for the Red Sox. His experience and leadership could be beneficial, especially in a young clubhouse, and if he can return to form, he could provide the power and consistency that Boston seeks.
5. Rhys Hoskins
Age: 32
2024 Stats: .214/.303/.419, 26 HR, 82 RBI, 149 SO, 53 BB (131 games)
Rhys Hoskins faced a challenging 2024 season after missing all of 2023 due to a torn ACL. Despite his struggles with the Milwaukee Brewers, his power numbers remained consistent, indicating that he still possesses the ability to drive in runs. With an $18 million player option for 2025, it seems unlikely that Hoskins would opt out after a lackluster campaign, but if he does, he could be an intriguing bounce-back candidate.
For the Red Sox, Hoskins could provide the right-handed pop they lack, and if he can regain his form, he could be a significant contributor to the lineup. His potential for a resurgence makes him a player to watch in the offseason.
Honorable Mentions
In addition to the top five, several other first basemen could make waves in free agency, including Carlos Santana, Justin Turner, Joey Gallo, Josh Bell, and Wilmer Flores. Each of these players brings unique skills and experiences that could benefit teams looking to strengthen their rosters.
As the offseason unfolds, the Red Sox and other teams will be closely monitoring these free agents, weighing their options, and considering how each player could fit into their plans for the 2025 season. The first base market is shaping up to be an interesting one, with plenty of potential for teams to enhance their lineups.
