This week's top seeds are Agnieszka Radwanska, Wimbledon and Olympic gold medal champion Serena Williams, U.S. Open titlist Sam Stosur and last year's Wimbledon winner Petra Kvitova.

Williams captured a pair of gold medals at the London Games two weeks ago.

"It was really awesome to win both medals at the Olympics," said the 30-year- old star. "I just want to keep playing well and doing the best that I can.

"More Slams obviously is what I want to go for. I definitely have goals that I want to try to reach," the former world No. 1 added.

Williams will face the aforementioned Daniilidou in the second round.

Russian star Maria Sharapova, who is not defending her title this week, beat 2009 winner Jelena Jankovic of Serbia in last year's Cincy finale.

The 2012 Cincinnati champion will earn $385,000.
