Sharapova to miss Birmingham

Birmingham: Maria Sharapova and Madison Keys have withdrawn from next week`s Nature Valley Classic in Birmingham as they look to regain full fitness ahead of Wimbledon. 

Sharapova, the 2004 Wimbledon champion, said she needed rest after reaching the French Open quarter-finals. 

The 31-year-old Russian served a doping ban in 2016 and was forced to skip the grass-court season last year with a thigh injury. 

American Keys, 23, will miss the Birmingham event due to an abdominal injury.
