World number one Novak Djokovic withdraws from Madrid Open to rest
It is the second consecutive year the Serb has pulled out of the tournament.
A statement issued by the organisers read: “He’ll take time out before continuing with his planned calendar.”
The Australian Open champion, 27, has been in fine form this year, becoming the first man to win the opening three Masters events of the season.
He hopes to complete the career Grand Slam with a first title at the French Open, which starts on 24 May.
