Script: SOUNDBITE (English): Stan Wawrinka, defeated Kevin Anderson 6-4, 6-4, 6-0:

"I was really happy the way I play. I was focused on doing what I wanted on the match. I was trying to be really aggressive on the return and make him play a mix or some slice, some aggressive play from the baseline."

SOUNDBITE (English): Stan Wawrinka, defeated Kevin Anderson 6-4, 6-4, 6-0, on how close he is getting to Roger Federer:

"I think the past three years, for sure, I get closer from him. My level improved a lot. I'm playing better tennis. So I was always really close from him, if we look Wimbledon last year. I will for sure need to play my best tennis. He's playing really well so far. He loves to play. He know how to play. He had some amazing match. It's going to be a big challenge. I think I'm ready."

SOUNDBITE (English): Stan Wawrinka, defeated Kevin Anderson 6-4, 6-4, 6-0, on the difference between facing Federer now and five years ago:

"I think now we both nervous when we enter the court. Before it was only me. I was nervous because I knew I wasn't at his level, for sure. And now I think we can see that he was also nervous every time we play each other the past few years. That's a big difference, because that show how much he knows that I can play at his level, how much he knows that I can try to play my game and not just try to react about what he's doing."

"You know, it's a very tough lesson for me today and, you know, it's difficult not to think about it, but obviously I have got to take what I can. This week has been a great week for me, the last two weeks. There is a lot of positives. I always try to look at that to obviously keep motivated and keep improving."
