Kiwi hit 23 aces yesterday.
I nearly forgot that the fans were booing him hard just because he left the court after the 4th set. I mean Djokovic did the same yesterday against Coria - on the same court (with the same fans?) - and he even got a bit applause when he came back.
And it was good to see that Kiwi seemed to have no problem with the heat. He moved well in the 5th set, Clement looked more tired.
