Batting practice is a perilous undertaking for Alex Rodriguez. Last season, he got nailed in the leg by a line drive off the bat of teammate Lance Berkman while exchanging waves with Joe Buck. Tonight, he got dinged on the back of the batting helmet by a BP foul that caromed off the side of the batting cage. Luckily, A-Rod was not hurt, although he did remove his batting helmet and rub the top of head, laughing. Then he took his regular swings without incident.
