Unfortunately out of greens - I actually find it pretty miserable that there are people who think there being a Scotsman who is one of the best 5 players ON THE PLANET isn't good enough.
At 23.
He didn't play very well, but Wawrinka is an extremely talented player with all the shots, who if he performs well against a counter-puncher can win - when he doesn't, he gets pumped. Just like Cilic and also Gasquet, who Murray also struggles against.
As Miles Maclagan said, he lost to a good player - it happens.
He'll win a major - and thankfully, it won't ever be Wimbledon.
