Roddick exits Memphis

 Top-seeded American Andy Roddick was outgunned 7-6 6-3 by Swede Robin Soederling after a battle of big-serving in the Memphis Championship quarter-finals on Friday.

Soederling, the eighth seed, trumped the Roddick's 15 aces by unleashing 16 of his own to seal victory in one hour and 25 minutes in an explosive match on the Stadium Court.

"We both served well and it was fun to play against him," Soederling told reporters after his first meeting with Roddick. "This is probably my favourite court on tour. I am serving great and I have no complaints at all."

Roddick predicted Soederling would now win the tournament.

"I thought if I would have gotten through that match, I've had a good chance of going the whole way," said Roddick, who never held a break opportunity.

"I certainly think he's going to go all the way."

Soederling will next face fourth-seed Radek Stepanek after the Czech beat Australian Chris Guccione 7-6 6-1.

Steve Darcis of Belgium fired down nine aces to crush Germany's Benjamin Becker 6-1 6-0 in the first quarter-final of the day.

The 23-year-old from Liege will face ATP Tour veteran Jonas Bjorkman in the last four, the Swede having battled past American Donald Young 1-6 6-2 7-6 in a two-hour contest.
