Fun the name of the game for Roddick

By Justin Palmer

LONDON (Reuters) - Andy Roddick has long had to deal with questions over his ability to add to his one and only grand slam success, but the American admits to reveling in his progress at Wimbledon this year.

The sixth seed eased into a quarter-final showdown with former champion and old rival Lleyton Hewitt by eliminating in-form Czech Tomas Berdych 7-6 6-4 6-3 on Monday.

Berdych had not dropped a set in three matches going into the clash but he had no answers to Roddick''s greater all-round firepower.

"I''m having so much fun... I love playing here, it''s an honor and something that is never lost on me," Roddick said.

"That''s the best I have played so far. I was really aggressive, I did a good job of moving the ball around. I was kind of in control of it the whole way... overall it was a pretty good performance."

This year''s Wimbledon is the 22nd major since Roddick''s triumph at the U.S. Open.

A runner-up here in 2004 and again in 2005, Roddick would not be drawn on how is game compared now to back then, preferring to look ahead to his clash with Australian Hewitt.

"I know that so far I''m happy with the way I''ve been going here. That''s probably my concern," he said.

Hewitt, who at 28 is two years older than Roddick, leads the American 6-5 from their 11 meetings dating back to 2001 but Roddick hold the upper hand in their last four meetings, including a victory in straight sets at Queen''s Club earlier this month.

"I have loads of respect for Lleyton, you know, what he''s been able to accomplish. Everyone knows he''s certainly capable of playing very, very, very well on this surface," said Roddick.

Hewitt has battled back from hip surgery and falling out of the top 100 in the rankings earlier this year, and Roddick said his progress at this Wimbledon was not a surprise.

"I don''t think anybody in the locker room would ever maybe at any point take Lleyton lightly, and especially on this surface.

"It certainly elevates him into one of the better players in this tournament. I''ve seen him play too much good tennis to have ever really let him drift too far from consciousness as far as the top guys go."
