Hugely gutsy win for Andy, keeps alive his hopes of Shanghai 
Trailed 3-6 4-4 and there was a huge game on his serve with a hell of a lot of deuces, saved 2 break points which would've ended his chances.
Then saved another 3 break points in the 3rd. First tiime in a while he's won a match which he probably should have lost, he doesn't do it often
Tough SF against Youzhny now, but certainly winnable.
