World number one Roger Federer produced a phenomenal display to see off a fired-up Andy Roddick in a stunning US Open quarter-final.
Roddick did not face a break point in the first two sets but Federer saved his best for the tiebreaks.
In the first, a backhand pass proved decisive and in the second, Federer crunched a return at Roddick's feet.
Federer finally broke at 3-2 in the third set before Roddick crumbled to his 10th straight defeat to the Swiss.

Roddick repeatedly hit crushing forehands to Roger's open court area on the forehand side.  What looked like a great shot was quickly

erased by Federer as he scampered over easily to smoothly swing a passing shot by the onrushing American.

Although Roddick served much bigger and better than in previous encounters, Federer was still able to out-Ace him, 15 to 14.
Roddick remained defiant after the match, saying: "I don't think it was a piece of cake for him. I thought I made him play as well as he could play.
"I'm not walking with my head down. I played my a** off out there. I played the right way. It helps, but that doesn't mean I can't be p****d off."
