With the Philadelphia Phillies lining up to make some potentially significant roster changes this offseason, not many players on the team should be safe from the trade block. The Phillies can't run the majority of this team back for another year after losing in the NLDS for a second consecutive season.
MLB insider Jayson Stark recently said that managing partner John Middleton and president of baseball operations Dave Dombrowski listen to the fans and he expects there to be changes this winter.
But who is the most likely to be traded by the front office this offseason? Here are some prime trade candidates for the Phillies to move to revamp the team heading into 2026.
3 players Phillies are most likely to trade with offseason roster changes looming
Alec Bohm
Alec Bohm has one more year of arbitration left on his deal with an estimated salary of $10.25 million. Dombrowski may look to trade him while he can still get some value in return for the third baseman, rather than losing him for nothing when he becomes a free agent.
Unlike last winter when Bohm trade rumors emerged, the Phillies will have a lower asking price for the 29-year-old this time, according to Stark. Bohm saw a drop in his statistics in 2025 compared to previous years. He had a career-high 44 doubles in 2024 compared to only 18 this season.
Bohm played in 120 games this year, his fewest since 2021. He excelled down the stretch of the regular season in September this season, unlike a year ago, when he slumped heading into the playoffs. The former third-overall pick hit .345 with a .905 OPS in September and had a much better performance in the NLDS than a year ago.
Brandon Marsh
Brandon Marsh may be on the move this winter. The Phillies see prospect Justin Crawford as their left fielder of the future and that the organization does not see Marsh as an everyday center fielder.
Marsh was an everyday outfielder at the start of this year, but the 27-year-old did not record any hits in April before landing on the IL. He did better as the year progressed and some of his numbers improved in 2025 compared to a year ago.
Marsh improved his OPS from .746 to .785, and his strikeouts decreased from 154 to 110. He finished with 25 doubles compared to 17 in 2024. However, he struggled offensively in October for the second consecutive year, going 1-for-13 in the four playoff games. If the Phillies choose to overhaul the majority of their outfield in free agency or via trades, they may decide to move on from Marsh.

Nick Castellanos
Nick Castellanos' time in Philadelphia appears to be nearing its end. He expressed his displeasure during the second half of 2025 when Thomson reduced his role, making him a part of an outfield platoon.
Castellanos said following his initial comments that winning the World Series is more important than his role on the club. However, it is difficult to imagine him accepting a part-time role with Thomson for a full regular season.
Castellanos also criticized Phillies fans at Citizens Bank Park following the team's NLDS Game 2 loss. There is a strong indication that he will be playing elsewhere in 2026 (subscription required), according to The Athletic's Matt Gelb.
The 34-year-old's numbers were down from previous years. His .694 OPS tied his full-season career low from 2022, and his 88 OPS+ was his lowest since 2013, when he made his MLB debut. Castellanos' -1.0 bWAR was the lowest of his career, while his fWAR was -0.6. His 34.5 percent hard-hit rate was his lowest since 2015.
Castellanos is entering his final season under contract next year before becoming a free agent. His $20 million salary is hefty, so the Phillies may have to agree to buy out a portion of his salary in a potential trade. At this point, it may be worth it, especially if they want to sign a top free agent outfielder.
