CC Sabathia threw 50 pitches in a four-inning simulated game Sunday morning at George M. Steinbrenner Field in Tampa, Fla., and the next time he steps on that mound will be Friday, his Grapefruit League debut. Sabathia, who had surgery to remove a bone spur in his left elbow last October, threw 50 pitches to Corban Joseph and Zoilo Almonte, and he figures to throw about 65 on Friday, when the Yankees host the Marlins. "Felt good today, no problems. I felt strong. I'm ready to go," Sabathia said. "I'm working pretty hard and trying to throw all my pitches and make it as game-like as possible. I'm getting good work out of it." The big left-hander hasn't had to see a doctor since he reported to Spring Training, and his throwing elbow hasn't bothered him at all during his last two throwing sessions. Sabathia said he threw a little bit harder Sunday than he had before this spring. "Hopefully, I can just keep getting stronger, velocity gets better every time and I'll have something to work with instead of 88 [mph] this year," Sabathia said.
