Peavy (back) played catch Thursday for a second straight day, Alex Pavlovic of CSN Bay Area reports. Peavy's ability to play catch on back-to-back days would seem to suggest he's close to moving it in for a flat-ground session, but the Giants reportedly plan to "slow play" it with him. Ryan Vogelsong will slot into the rotation in his place for now. An MRI last weekend showed a muscle strain as well as continued issues with the SI joint in Peavy's lower back.
