Tennis-Davenport, Williams sisters out of San Diego

SAN DIEGO, July 29 (Reuters) Lindsay Davenport and Venus and Serena Williams have withdrawn from next week's Acura Classic in San Diego, the WTA Tour announced.

Venus Williams, a three-times champion at the event, has withdrawn due to pain in her left wrist.

''I am training and rehabilitating and look forward to being back on the Sony Ericsson WTA Tour as soon as possible,'' she said yesterday.

Serena, who played her first tournament in over six months last week in Cincinnati where she lost to Vera Zvonareva in the quarter-finals, said her sore left knee is not ready for consistent play.

''I am just coming back from injury and my doctor has advised me against playing too much too quickly,'' said Serena, who had accepted a wild card into the Acura.

''This is frustrating as I am eager to improve my ranking and play more tennis but it is something I must do.'' Davenport has been sidelined with injury since March with a back injury.

All three Americans are entered in the Los Angeles tournament the week after San Diego.
