Key Biscayne, Fla. — A limping Serena Williams often found herself out of position and forced to hit awkward shots. She iced her left thigh during changeovers and twice received treatment from a trainer.
But Williams kept playing. Quitting her quarterfinal match Wednesday against Jennifer Capriati at the Ericsson Open was not an option.
Her sore thigh and some stinging forehands from Capriati spoiled a potential final Saturday between the Williams sisters. The fourth-seeded Capriati won 6-1, 7-6 (5) and advanced to today's semifinals.
The Williams sisters were supposed to play in the Indian Wells semifinal March 15, but Venus pulled out with knee tendinitis, prompting speculation she ducked the match.
"We got some bad press for that," Serena Williams said, "so I decided to go all out."
Second-seeded Lindsay Davenport retired with a bone bruise in her right knee while trailing No. 7 Elena Dementieva 6-3, 1-0 in the last women's quarterfinal.
Dementieva will play Capriati today, and No. 3 Venus Williams will renew her rivalry with No. 1 Martina Hingis.
