"I’m really happy with my level today, I was serving and moving well,” said Wawrinka.
"He’s always been a tough opponent. I saved match point in St Petersburg [last month], saved match point in the  US Open, three sets in Indian Wells [last year], tough sets today. It’s not easy to get through him. But I think today was one of my best matches against him."
Evans had two break points at 1-1 in the first set but failed to convert. The British No 1 was then broken in the next game and couldn’t get back into the set.
