Fourth-seeded Lindsay Davenport, playing her first WTA event on US soil in two years, swept aside Danish teenager Caroline Wozniacki 6-0, 6-2 in the Memphis Championship quarterfinals on Thursday.
The 31-year-old American broke her 17-year-old opponent, the sixth seed, three times in the first set before sealing victory in 53 minutes.

Davenport, who returned to the court last September after an 11-month absence to have a baby, will meet New Zealand's Marina Erakovic in the last four. Qualifier Erakovic earlier came from behind to beat Russian Alla Kudryavtseva 4-6, 6-3, 6-3.

In the other women's quarterfinals, third seed Shahar Peer of Israel battled past seventh-seeded Swede Sofia Arvidsson 3-6, 6-1, 6-3 and fifth-seeded Olga Govortsova of Belarus beat German Julia Goerges 7-6, 6-2. In the men's draw, top-seeded Andy Roddick blasted past fellow American Mardy Fish 6-4, 6-2 in a second-round match.
Roddick unleashed 14 aces to cruise to victory in just over an hour and book a quarterfinal meeting with eighth-seeded Swede Robin Soederling, who crushed Victor Hanescu of Romania 6-2, 6-1. Chris Guccione fired down 15 aces to upset sixth seed Thomas Johansson of Sweden 6-3, 6-4 while veteran Swede Jonas Bjorkman beat fifth-seeded American Sam Querrey 6-4, 4-6, 7-6.

Bjorkman faces American Donald Young, a 6-1, 1-,  6-3 winner over Colombian Alejandro Falla.

Henin ousted

World number one Justine Henin’s unbeaten run of 17 matches at the Dubai Open came to an end as she went down 6-7 (3-7), 6-7 (4-7) in the quarterfinals to Francesca Schiavone, adds AFP from Dubai.

Henin had never lost in seven previous matches to Schiavone but despite having a point to break serve early on and making a brave late revival, she was too inconsistent to deny her aggressive, in-form Italian.
Spectator warned

Meanwhile,  a spectator suspected of involvement in illegal betting was threatened with ejection during Henin’s shock defeat .

Henin’s loss was her first in 18 matches and five years at Dubai and her first to the Italian, and during it a man in the stands was watched at length talking on a mobile phone.

He was then spoken to by a WTA Tour official as he sat in his seat, before the two left to continue the discussion elsewhere. It was said to be the second such incident in the centre court stadium two days. “I spoke to a man who seemed to be giving a commentary on the match over his mobile,” said John Dolan, senior communications manager of the WTA Tour. The man apparently claimed not to understand what was being said in English, according to Dolan, who then communicated with him in German.
