J.D. Drew is eager to test his hamstring, but he will be cautious with the injury. Drew managed to stay off the disabled list in 2010, but his performance suffered in the second half, when he batted just .231 with a .318 on-base percentage, a .421 slugging percentage and a .739 OPS. "I got that chronic hamstring stuff I was dealing with at the end of last year," he said. "The second half of the season, I missed some games with it. It just didn't seem to want to go away. "I can deal with it if it's slightly tight or something, but what it was was chronic irritation up high in the hamstring behind the glute [gluteus muscle]. That was basically like tendons rubbing. It caused tendinitis. We tried everything as far as treatment last year."
