Kershaw’s back stiffened in the weight room on Tuesday. The southpaw felt better on Wednesday, but manager Dave Roberts said he “didn’t think it was safe to start him. Roberts said the team were erring on the side of caution, but didn’t know how long Kershaw will be out.Kershaw would have made his ninth opening day start for the Dodgers. He also missed opening day last year when he started the season on the injured list with inflamed left shoulder. He was replaced by Hyun-Jin Ryu, who signed with Toronto in December.
Kershaw is 5-1 with a 1.05 ERA on opening day.
May was dropped from the Dodgers’ 30-player roster earlier in the day after being switched to the team’s alternative training site earlier in the week. Outfielder Terrance Gore was called up in place of May.
