Red Sox's Vaughn Grissom: Turning corner

Red Sox manager Alex Cora said Wednesday the team hopes to start planning a minor-league rehab assignment for Grissom (hamstring) toward the end of the week, MLB.com reports.

Grissom has been building strength in both hamstrings and appears to have turned a corner in his recovery. Cora believes Grissom's issues may be related to his winter preparation, which was different compared to previous offseasons after being acquired from Atlanta.
