American Serena Williams, the number 10 seed, returned from a left ankle injury and defeated China's Zhang Shuai 6-2, 6-3 at the 2012 Sony Ericsson Open. Serena fired six aces and connected on 64 percent of her first serves, while dropping only one service break to advance in just one hour and 20 min. Serena advances to face the 21st-seed, Italy's Roberta Vinci, in the third round. Serena, 46-0 in first-round matches at Grand Slams, improved to 12-0 in opening round action at the Sony Ericsson event.
"I was a little bit rusty and a little bit nervous too," Serena said. "I haven't played here for so long, and I wanted to do well. So I was really nervous out there, but I think now I've gotten one under I'll be better."
Also advancing on the women's side of the draw was Belgium's Kim Clijsters, a 6-2 7-5 winner over Germany's Julia Goerges, and Russia's Maria Sharapova, a 4-6, 6-3, 6-3 winner over Israel's Shahar Peer. The world's number two-ranked Sharapova will next face American Sloane Stephens, who ousted Italy's Sara Errani, 3-6, 6-2, 7-5.
Former world number one-ranked Caroline Wozniacki also advanced to the third round with a 6-4, 6-0 win over Czech Barbora Zahlavova Strycova.
