Funny guy that commentator... Did he really say that seriously???
Yes, he was dead serious. He's actually pretty good, he drives me nuts, but he knows his tennis and gives tons of technical details about their racquets, the strings they use, what they practiced more in their last training sessions before the match, etc.
But he doesn't seem to know Gilles very well. Maybe he talked with Tulasne before the match, I can totally picture Tulasne saying that.
