I know. Because you're always used to being active, but you need to give your body a chance to recuperate. So rest MsA. Granny's orders!
I really thought he was going to pull that 2nd set around, but once Tipsarevic had got the breaks back you could pretty much see the writing on the wall. Didn't see anything of the Dimitrov match so I couldn't tell you Amber. Unless his matchplay from the previous weeks had caught up with him. Even so, that was a match which shouldn'tt've been decided in straight sets.
