Serena Williams is regaining her form after being slowed by an ankle injury following the Australian Open, and is seeded eighth. Venus is seeded 10th, having played only eight matches since winning Wimbledon.
"I'm feeling actually the best I've felt in a really long time," Serena Williams said after beating Schiavone. "I wish I could have gotten those drop shots. I just couldn't get them. Next time."
Still, the victory was some sweet revenge. Williams lost to Schiavone in May in a loss she called the worst of her career. Recovering from an ankle injury and playing her first match in a month, Williams looked lethargic and powerless in a 7-6 (2), 6-1 loss to the Italian in a clay-court tournament in Rome. She withdrew from the French Open the following week. She looked much better Friday, playing her best match so far at the Open.
