Former No. 1 Caroline Wozniacki advanced to the US Open quarterfinals after her good defense beat good offense from Maria Sharapova.
She showed flashes of her old brilliance, but the 34-year-old Venus Williams, who has been busy with doubles, dug a hole and couldn't quite escape in a third-round loss to Sara Errani at the US Open.
Sara Errani was frank in admitting that she couldn't handle the pressure of being the US Open's No. 4 seed during a second-round loss to Flavia Pennetta.
Good news for tennis fans: Serena Williams and Victoria Azarenka seem destined for another battle of the wills, this time in the US Open finals.
The Williams sisters seemed down and out, but 2012 proved to be a career year for Serena Williams. Her comeback was the biggest story of the year, but not the only one.
Victoria Azarenka outgrunted Maria Sharapova to win in three loud sets, while Serena Williams lost just three games in her semifinal against No 10-seeded Sara Errani.
No. 10 seed Sara Errani is hoping her new racket, "Excalibur," will help her magically overcome Serena Williams in the U.S. Open semifinal.
