CC Sabathia lost 25 pounds this season, which the left-hander says has improved his stamina. "My stamina, especially coming out of the bullpen and going straight to the mound, I feel good," Sabathia said. "I just don't get tired. Early in spring training years past, I would get a little gassed in my bullpens getting later into the 'pen." After warming up on a bullpen mound, Sabathia threw 25 pitches during his first batting practice session Thursday. "My bullpens are better," Sabathia said. "Thirty, 40 pitches in and I feel pretty good, and I was able to keep my mechanics together and work on stuff I needed to work on. My pitches weren't doing anything different. It's all the same. My stamina is a little better."
