Florida: Top-ranked Caroline Wozniacki won her opening match at the Sony Ericsson Open by beating Bethanie Mattek-Sands 6-2, 7-5 on Thursday.
Wozniacki, coming off her 14th career title last week at Indian Wells, erased eight of the 10 break points she faced. She hit only five winners but committed just 15 unforced errors to 49 for Mattek-Sands.
"Bethanie is a tough player to play," Wozniacki said. "You never know what to expect from her, and she's going for her shots no matter where she's standing on the court, and it's difficult to get the rhythm."
