The Boston Red Sox showed a lot of improvement in 2025. They made the playoffs for the first time since 2021 but lost to the rival New York Yankees in the American League Wild Card round.
This offseason is an important one for the Red Sox if they’re going to keep pace with the Yankees, the American League champion Toronto Blue Jays and the other top contenders in the sport.
The Red Sox have already made a few additions to their roster in recent weeks, including starting pitchers Sonny Gray and Johan Oviedo.
Boston still needs to add another bat, especially one with power. One storyline to follow is whether the Red Sox bring back third baseman Aleg Bregman.
And with a strong farm system, will the Red Sox use any of their top prospects to make a major splash in the trade market?
