Caroline Wozniacki unhappy as Maria Sharapova gets prime time billing at US Open

Caroline Wozniacki has criticised the US Open for giving Maria Sharapova prime-time billing following her return from a doping suspension.

The US Open broke ranks with the other grand slams by awarding Sharapova a wild card and the five-time grand slam champion has played both her matches on Arthur Ashe Stadium, the biggest arena in tennis.
