There has been some concern as to whether or not Peavy would be able to make the start as he has been dealing with some lower back discomfort. On Wednesday Peavy threw a bullpen session and both sides came away happy with the results.
Bochy: Belt could be available to pinch-hit as soon as today. Peavy on track to start Sunday. Maxwell/Duffy start cuz of Hellickson splits.
