Caroline Wozniacki is doing everything she can to get back to her best fitness.

The Dane is working hard to get in the best possible shape before playing her first tournament of the new season in Auckland. The ASB Classic has a packed line-u with top names such as Caroline’s great friend Serena Williams, Bianca Andreescu, and rising star Coco Gauff.

Last year in Auckland, Caroline was stunned in the 2nd round by Andreescu that was completely unknown by most tennis fans and she was coming straight from the qualifications. The result was rather straight forward 6-4 6-4.
