Sharapova playing with bad shoulder

When Maria Sharavpova's shoulder tendonitis didn't heal, her doctors told her to take another four to six weeks off, or get a steroid shot so she could play in the French Open. She chose the shot. From what I've seen on television, however, it looks like she might have been better off to extend her vacation; she is having obvious problems with the shoulder, which is inhibiting her serve. Too bad. It's not like Sharapova would have won the French Open, but I don't like seeing her playing while wounded.
