4. Pete Crow-Armstrong
Chicago Cubs starting center fielder Pete Crow-Armstrong is probably going to be the breakout player on the team's roster in 2025.
It's been a gradual ascension for Crow-Armstrong this season in his efforts to become a starting outfielder at the Major League level. Crow-Armstrong's offensive struggles to open the season suggested that the Cubs may be in trouble, but his resurgent second half of the season has placed him firmly into being in the conversation to be the Cubs' best blue-chip player.
Even as Crow-Armstrong's offense has turned the corner this season, he has remained near the bottom of the team's starting lineup. Given the speed that he has, the next step for Crow-Armstrong may be getting as many plate appearances as possible.
As the Cubs' focus shifts to the 2025 season, Crow-Armstrong will be a player that the front office circles as a reason for optimism.
