Man, Wawrinka is SO good. There's no one I enjoy watching play more than him right now. If he had the head of Djokovic, Federer, or Nadal, he'd be the best player in he world. He's got more in his arsenal than any of those guys. He had some bad stretches today, which will always happen in a long match against a great player, but when he's playing like he did the last 2 matches, the people that can beat him are Djokovic, Nadal, and maybe Federer. That's it.
The semi today was about as razor thin a margin as you can get. A couple of mental lapses cost Wawrinka the match. They're the things the elite players rarely do. He was down 5-4 in the 3rd set and was up 40-15 in his service game and had a couple of bad errors to lose the game, which lost the set. He was having his way with Novak the end of the 4th set, then almost broke him the first game of the 5th. He then double faulted twice to lose his first service game. I think it was pretty much over at that point. He's a mental lapse here and there away from winning multiple slams. I'm afraid he's found this new level of his game a little too late in his career.
