(Milwaukee, WI) — Brewers’ left fielder Ryan Braun is injured again, leaving Wednesday night’s game with a tight left calf in the fifth inning. He ran slowly to first base on a single — and it came right after Braun returned Tuesday night from a strained flexor in his right forearm in which he missed six games. After hitting seven home runs in April, Braun has only had eight plate appearances so far in May. Manager Craig Counsell says he hopes the calf injury is not serious, and he was planning to give Braun a scheduled day off when the Brewers host Boston this afternoon. Meanwhile, Milwaukee starter Junior Guerra will begin a minor league rehab assignment Monday at Double “A” Biloxi, after throwing a 60-pitch simulated game Wednesday while recovering from a calf injury on Opening Day.
