Caroline Wozniacki was once the No. 1-player in the world, but at the age of 22, her career is headed in the wrong direction.
She was ranked No. 8 in the U.S. Open coming into the tournament, and there's a good chance she falls out of the top 10 completely after she was upset by the unseeded Irina Camelia-Begu on Tuesday night.
She lost in straight sets 6-2, 6-2 and needed a trainer to look at her knee in the middle of the second. Her game was clearly off: she had only four winners compared to two unforced errors.
Camelia-Begu, a 22-year old from Romania, was the beneficiary of Wozniacki's struggles, as she racked up one of the biggest scalps of her young career.
Wozniacki's loss could open up her side of the bracket to American Sloane Stephens, a 19-year old who many think could one day become the next Serena Williams.
