Giants Manager Bruce Bochy says Yusmeiro Petit will start in Cain's place for the second straight time Saturday. Bochy anticipates Cain will make his next start at home June 6 against the New York Mets.
Bochy says Cain was willing to pitch but admitted he was still feeling something in the hamstring. Bochy says if it was mid-September and the Giants were in a tight race, Cain would have pitched.
Cain is 1-3 with a 3.66 earned-run average in eight starts. Petit is 3-2 with a 5.08 ERA in 14 games, four of them starts.
