He was cooked the first two sets and played like garbage. A WTA player would have beaten him in those sets.
Third set he was playing well. Had many set points and Novak didn't rip anything out of his arse like against Nadal to save them. To me that is mental for Anderson. He was clutch against Federer, however is known for not being mentally strong in plenty of tour finals in the past.
Well done to Novak, good that he's been able to make a comeback after all the various problems he's had in recent times. Would have been great to see the underdog win but I think Anderson played his final in the Semi.
