Of the three mentioned I think Wainwright deserves it the least. The race should be between Carpenter and Lincecum. Carpenter has fewer starts, innings and a worse k/9 stat but Lincecum has much worse road stats, including allowing all his homers on the road (10) as well as having a road ERA of nearly double that of home (3.21/1.88). In fairness to Lincecum, the Giants provided little run support having one of the worst offenses in baseball while the Cardinals offense is closer to being middle of the pack. Lincecum had 11 quality starts where he took either a loss or no decision. Carpenter had eight such starts. In all I think Carpenter deserves it more though. The home/road splits are the difference for me.
