Peavy (back) will make another rehab start at Triple-A Sacramento on Tuesday, Amy Gutierrez of CSN Bay Area reports. It will be the fifth rehab outing for Peavy, and his fourth with Sacramento. He's been hit hard during each of his starts at Triple-A, but a 15:4 K:BB ratio during his three turns suggests he's doing a good job of finding the strike zone. After building his pitch count to 83 his last time out, Peavy figures to reach the 90 or 100 mark Tuesday while covering around six innings. If he notices no setbacks during the outing, he'll likely make his return to the Giants over the weekend, though it's unclear if he'd displace any of the team's current rotation members.
