Right shoulder is basically Sabine's meal ticket.
Without healthy right shoulder, she has no monster first serve or powerful forehand.
Sharapova had right shoulder injury. How long did that take to heal?
Sabine already had problems with her right shoulder as she retired in her match against Grönefeld in Estoril!
The break back then wasnt that long, after one week she was ready to play again!
But that it is the same injury now, that is not a good sign, maybe she needs a longer break to recover this time...although I think that she can play the US Open for sure, even so the problems with her shoulder could come back anytime after she played a few matches/tournaments in a row!
