In absence of Roger Federer,Wawrinka carries Swiss hopes at US Open

Wawrinka,the player constantly living in the shadow of 17-time grand slam winner Roger Federer in his homeland,was blown off the court by Berdych in the first set.

But in a match featuring superb ball striking and a combined 68 winners,Wawrinka8217;s consistency proved the difference against the tall Czech.

He closed out the match by breaking Berdych8217;s serve for the sixth time to set up a quarter-final against Britain8217;s defending champion Andy Murray.

It is the first time Wawrinka has progressed further at a major championship that Federer,who was ousted by Spain8217;s Tommy Robredo in the fourth round.

8220;It8217;s a different situation,for sure,8221; Wawrinka told reporters. 8220;I8217;m really happy for myself this year,with what I8217;m doing right now,but I would prefer to have him still playing in the tournament.

8220;I watched his match yesterday and it was not that good. I was sad for him,because he8217;s a good friend and I like when he8217;s winning grand slam titles. I hope he will come back stronger.8221;

Wawrinka said he was in career-best form ahead of his clash with Murray.

8220;I think I play my best tennis ever,8221; he said.

8220;Andy is a really good player. We practice a lot together. We have some really great battles when we play each other. I like to play him. I like his game. I think if I start well,if I stay with him,I have a good chance.

8220;I need to start well to show him I8217;m going to be there.8221;
