At the French Open at Roland Garros, the much awaited fourth round showdown between 23-times Grand Slam champion Serena Williams and former world number one Maria Sharapova failed to happen, after Williams was forced to withdraw through injury.
William said: "Yeah, I, unfortunately have been having some issues with my pec (pectoral), my pec muscle, and unfortunately it's been getting worse, to a point where right now I can't actually serve. So, it's kind of hard to play when I can't physically serve."

The surprise of the day came with the defeat of Caroline Wozhniacki - the Australian Open champion was eliminated by Daria Kasatkina from Russia.
