Yoshida underwent surgery Oct. 3 to repair a labral tear in his right shoulder, Ian Browne of MLB.com reports.
The hope is that Yoshida will be ready in time for Opening Day, although it's not clear how limited, if at all, he will be during spring training. Yoshida slashed .280/.349/.415 with 10 home runs over 108 games for Boston this season as its full-time designated hitter.
