John McEnroe once said that Wawrinka has "the best one-handed backhand in the game today." I think shots like that last one are where he gets that from. A ridiculously good effort down the line to force deuce on the Murray serve.
Told you Murray was not happy...
Murray struggling from this end of the court. Maybe the wind is playing a part, not sure but he certainly looks weaker down this end. 0-30.
A challenge goes Murray's way. Could this be the spark he needs to fight back. Clutching at straws a bit?
Clenched fist from Wawrinka has he comes from 0-30 down to level.
A glimmer of hope as Wawrinka misses his first serve, but Murray puts the second serve into the net.
He never really got going today and it is game over for Murray. Beat, well beaten, in straight sets.
A superb performance from Wawrinka. He is in the form of his life and is now in his first ever Grand Slam semi final at the age of 28. Must be due to beat his career record of 9th in the rankings too.
