Yankees manager Joe Girardi admitted to reporters Wednesday that he still had doubts that starter CC Sabathia could muster the energy and strength to endure walking to the mound on just three days' rest. 'I'm fairly sure he can make it about halfway to the mound, but he's going to be exhausted,' said Girardi, expressing concerns about the wear and tear on his ace pitcher's body. 'Usually he only makes it without collapsing on four days' rest, but this is the ALCS, so he might just have to gut it out. Either way, we are going to keep a close eye on his step count.' Girardi said he planned to have Sabathia conserve energy by sitting down between pitches, and intended to have seven or eight players carry the 2007 Cy Young winner into the dugout after each inning.
