Davenport, Serena Limp to Exit

MIAMI — Second seed Lindsay Davenport and fifth seed Serena Williams limped out of the quarterfinals of the Ericsson Open with injuries Wednesday, allowing Australian Open champion Jennifer Capriati and Russian Yelena Dementieva easy wins.

Dementieva advanced to the semifinals for the second time in three tournaments when Davenport suddenly retired from their match with a knee injury while trailing 6-3, 1-0.

The victory will propel the 19-year-old Dementieva to a career-high of eighth in the world rankings.

Davenport will slip to No. 3 with Venus Williams, who booked her place in the semifinals Tuesday with a win over Yugoslavia's Jelena Dokic, taking over the second spot.

Davenport, who lost to world No. 1 Martina Hingis in last year's final, displayed no signs of distress early in the opening set, breaking the Russian to take a 3-2 lead.

But the seventh-seeded Dementieva at once broke back, and broke again in the eighth game to take the first set.

When Dementieva broke Davenport to open the second set, the three-time Grand Slam winner stopped the match.

Davenport said the injury will take 7-to-14 days to heal and does not expect it to affect the upcoming claycourt season.

It was a busy day for the trainers at the $6 million tournament.

Earlier in the day, Capriati had swept to a 6-1, 7-6 victory over a struggling Serena Williams.

Williams had the WTA trainer on court twice for treatment for a left thigh injury, which she said first flared up on the way to her Indian Wells title nearly two weeks ago.

The fifth seed was clearly seen wincing, particularly when serving at the end of the one hour, 31-minute quarterfinal, but felt she had no choice but to play.

"I've just been going on like a soldier," Williams said. "I hurt it at Indian Wells and I've been struggling ever since."

Williams said she considered not playing. "But because we've had such bad press lately I decided to go on."

Capriati, who also called for the trainer during the match because of blisters, will meet Dementieva in the semifinals.

In men's quarterfinal action, seventh-seeded Australian Lleyton Hewitt ended Andy Roddick's title dreams with a convincing 6-3, 6-2 victory.

Next up for Hewitt is another promising young American, Jan-Michael Gambill, who saved a match point before beating Argentina's Gaston Gaudio 3-6, 7-5, 6-4.
