Because they can't get or defend their trophy, they should withdraw next tournaments to make a self-examination to prevent do it again. For example, Mary Pierce since lost to Li Na in three years ago of US Open (she won the first set 6-4, she should won next set to face against the eventual champion Maria Sharapova in next round, but she lost the two set 0-6 fairly), she should take a rest at least three months. But she as usualy played next three tournament (include Luxembourg, Stuggart and Zurich), as a result she lost to her opponents (A. Bondarenko, Jankovic, Srebonik) in first round consecutively!! What do you think?
