A review of the rest if the men's singles on day 10 of the US Open, including a career-ending defeat for Andy Roddick.

Andy Roddick: Defeated by Juan Martin Del Potro

Roddick's career was brought to a close with defeat to Juan Martin Del Potro in the fourth round of the US Open.

It was fitting that the American's final moments in tennis should be played out on Arthur Ashe Stadium, the court where he enjoyed his biggest success when he won the title in 2003.

The match had begun yesterday before rain interrupted and for a while he looked like he might extend his career in glorious fashion with victory over the seventh seed.

They resumed in a first-set tie-break and Roddick dropped only one of the first seven points, but Del Potro levelled and from there the Argentinian was in control.

Roddick saved a match point to huge cheers from the patriotic crowd but it was not to be as Del Potro won 6-7 (1/7) 7-6 (7/4) 6-2 6-4 to set up a last-eight meeting with second seed Novak Djokovic.

Defending champion Djokovic finally made it through to the quarter-finals after Stanislas Wawrinka retired in the third set of their match.

The pair had begun their fourth-round clash on Tuesday night before rain brought a premature end to play and they were on and off the court again before the match finally resumed just after 1pm on Wednesday.

Djokovic was tested in the first set but after that it was a one-sided contest and Wawrinka called it a day with the second seed leading 6-4 6-1 3-1, although the reason was not immediately apparent.

They managed only two games before the rain came on Tuesday, Djokovic winning both of them, but Wawrinka quickly retrieved the break on the resumption.

The last time the Swiss beat Djokovic was six years ago and his cause was not helped when he promptly dropped his serve again.

Djokovic has cruised through the draw in New York but he was making more unforced errors than usual on a sparsely-populated Louis Armstrong Stadium and was unable to serve out the set.

However, for the second time Wawrinka failed to hold serve straight after breaking and things swiftly went downhill in the second set for the 18th seed.

After saving a break point in the opening game, Djokovic reeled off four games in a row, and Wawrinka responded by smashing his racquet on the court.

It did not help, though, and he was quickly a break down in the third set. Wawrinka talked to the trainer after the change of ends and, following the fourth game, he called Djokovic to the net and shook hands.

Janko Tipsarevic faces David Ferrer in the quarter-finals after defeating Philipp Kohlschreiber 6-3 7-6 6-2.

"It was just a two‑day match, and I'm extremely happy that I managed to go through in straight sets," said the Serb.

Tipsarevic is now expecting a tough test from Ferrer,

"It's going to be a really, really difficult battle, because both of us are groundstroke players," he added.

"We don't have huge, huge weapons, so I think a guy who is tactically better and mentally stronger is going to be the winner tomorrow.

"I expect a very difficult match."
