Western & Southern Open Officials say Rafael Nadal, the tournament defending champion, has withdrawn due to a wrist injury.
Nadal, currently ranked #2 in the world, says he is disappointed:
"Unfortunately I injured my right wrist yesterday during practice and after the tests I have undergone today in Spain, including an MRI, and checking with my doctors, I will have to stay out of competition for at least 2-3 weeks. I am sorry and wish the best to the tournament and thank all of the fans for their support."
