Caroline Wozniacki's best showing at a major was a loss in the 2009 U.S. Open final to Kim Clijsters.

Happy birthday, Caroline Wozniacki. The Danish tennis star and former world No. 1 turns 23 today. She has spent 67 weeks of her young life as the top-ranked player in the world. Wozniacki has won 20 career singles titles but is still in the hunt for that elusive first major. She is currently ranked 10th in the world. Her last title came in October of 2012, when she beat Sam Stosur in the final of the WTA Kremlin Cup in Moscow.
