For Serena Williams, a win in Sunday's US Open final would mean a place alongside legends Chris Evert and Martina Navratilova with 18 majors. For Caroline Wozniacki, a win would provide validation to her longtime reign as No. 1.
Playing a more aggressive style, former No. 1 Caroline Wozniacki dropped just one game against Sara Errani, advanced to the US Open semifinals and took another step toward her first career Grand Slam title.
