By Conor Roche MLB’s offseason is officially here. The offseason commenced late Wednesday night when the Dodgers put the finishing touches on their five-game World Series win over the Yankees.

The Red Sox won’t be losing a core player in free agency this offseason, but they have a handful of players who made noticeable contributions to the team last season hitting the open market.

He recorded 27 saves last season, serving as the Red Sox’ closer for the last two years as he’s set to become one of the best relievers available in free agency. It seems likely that Jansen’s days in Boston are over, though, considering how the 2024 season ended.
