Stan Wawrinka: I think I showed unbelievable fight tonight. Saving match point was tough. He's really talented, was pushing me a lot and there was a lot of pressure to stay in the match.
"I tried to dictate play a bit more at the end but I am really happy to finish like that. I had to stay positive and find some mental fight to stay in the battle."
