Top Seeds Advance in RMKC/CSC Tennis at the Racquet Club

MEMPHIS, Tenn. (AP) - Top-seeded Andy Roddick moved into the

quarterfinals of the Regions Morgan Keegan Championships with a 7-6

(2), 6-4 victory over Yen-Hsun Lu of Taiwan on Thursday night.

Roddick, pushed to three challenging sets in a first-round win

over James Blake, advanced to the quarterfinals in Memphis for the

ninth straight year. Roddick, the world's seventh-ranked player, is

the tournament's defending champion.

Roddick relied on 10 aces and a key break of serve to beat Lu,

who at No. 114, was one of the lowest-ranked players in the 32-man


After failing to break Lu on seven earlier opportunities,

Roddick converted on the eighth by double-fault. The mistake by Lu

gave Roddick a 5-4 lead in the second set. He served out for the

match, winning on an ace.

"It was good. But if I want to go further in this tournament

I've got to do better on break points," Roddick said. "That was

really ordinary. The one I ended up getting was because he doubled.

"I'm doing a good job of getting (break points). I feel like

I'm in every (opponent's) service game, but I can't miss

second-serve returns at 15-30 or 30-all. I'm very close to playing

really well. It's just a matter of tightening things up to make

that happen."

Other seeds advancing to the quarterfinals were No. 5 Tomas

Berdych and No. 8 Sam Querrey. Berdych defeated unseeded American

Michael Russell, 3-6, 6-3, 6-2 and Querrey beat Argentina's

Leonardo Mayer, 6-4, 6-0.

In the women's portion of the event - the Cellular South Cup -

top-seeded Maria Sharapova continued her dominating march with a

6-2, 7-5 victory against Elena Baltacha of Great Britain to reach

the semifinals.

Sharapova, the world's 16th-ranked player, has not dropped a set

and lost only 11 games in three matches in her first tournament

since losing in the first round of the Australian Open last month.

Second-seeded Melanie Oudin, the 18-year-old American who

stunned Sharapova at last year's U.S. Open, was upset in the

quarterfinals by qualifier and 2006 Memphis champion Sofia

Arvidsson of Sweden. Arvidsson, who barely made it to Memphis in

time to compete in the qualifying, won 6-1, 6-3.

Arvidsson, ranked 139th, had to rush from a $100,000 total prize

money minor tour event in Midland, Mich., to participate in the

qualifying, which began Friday.

"I didn't arrive until an hour and a half before my

qualifying," she said. "I almost didn't make it into the

tournament. I've been lucky this week. I've been fighting through

my matches. It's been unbelievable."
