Alex Rodriguez re-injured his quadriceps in the Yankees' win over the Indians on Monday and will likely sit out against the Tigers on Tuesday night, according to ESPN.com. "The key for me now is to get healthy," Rodriguez told MLB.com. "There's a lot of baseball to be played this year. When I get back out there, I want to be close to 100 percent." He played all four games against Cleveland. "Every time he has to run, you see it sometimes," Manager Joe Girardi said. "He said every day, when he come back the next day, it feels better. There have been times when you see him run and you see him pull up a little bit. We're trying to tell him to be smart."
