Boston Red Sox third baseman Rafael Devers was placed on the 10-day injured list Saturday with left shoulder inflammation, the team announced, likely ending his season.
Devers left Friday night's 12-inning loss to the Minnesota Twins in the top of the 11th. The slugger went 1 for 4 with a walk and three strikeouts.
Saturday's game against Minnesota was postponed because of rain. It was rescheduled as part of a Sunday doubleheader.
Speaking before the game was rained out, Red Sox manager Alex Cora said Devers tweaked his shoulder while working in the batting cage and tried to play through it.
"He made some adjustments throughout and yesterday he was like, there wasn't much there," Cora said Saturday. "Today, actually, we talked about something I saw mechanically, and he was very honest about it. The bat speed, it wasn't there. We can see it."
The Red Sox are five games out of a wild-card spot in the American League with eight regular-season games remaining.
Devers, who turns 28 next month, slashed .272/.354/.516 with 28 home runs and 83 RBIs this season.
