definitely, star... it's good for him both in terms of match play and his confidence in general. Yay
But I would not classify his performance today as having played "real well" - to me you could see his discomfort on the surface. he doesn't move nearly as well as on clay or even hardcourt and yeah, just didn't look solid. But that will come with time.
It's disconcerting that he was rubbing his shoulder/pec though. I hope nothing is wrong.
