After the match Roger Federer said: 'Against Kei, in the first set we were both playing very badly - we can't play much worse than that. Kei actually played very well at the end. He just had the better attitude and played a little better. Today I was happier, I love playing here.'
The Swiss will face in the next match Kevin Anderson who defeated Kei Nishikori 6-0 6-1 on Tuesday and already beat him at Wimbledon this year in July.
