After throwing his first bullpen session with the Yankees since returning to the club last week, Andy Pettitte said afterward, "I feel like I never left." The left-hander ended his one-year retirement by signing a minor league contract last Friday. "I am a little surprised that I felt as good as I did today, to tell you the truth," he said. "So we'll just have to see where it goes -- hopefully it will continue to be that good." After undergoing a physical exam Tuesday morning, Pettitte threw approximately 50 pitches. "That's as good of a bullpen as I've caught all spring," said Russell Martin, who caught most of the session. "He threw all his pitches, and just kept executing pitch after pitch after pitch."
