If Murray wins his QF, I'm not sure he'll have much left for his doubles SF with Rojer. Unfortunate, but that's always a risk when partnering with a singles player.
According to the commentators on tennistv, Rosol threw an "expletive" at Andy when Andy complained to the umpire. I do think Andy made a bit too much fuss about it, but it was a quite deliberate and heavy barge - it knocked Andy sideways a bit. The barge was only because Rosol, having won the first set, decided literally to throw his weight about. He does have the reputation of being a bit of a thug.
