Because they lost a match is not acceptable (e.g. lost a match point, lost a second set when they were leading their opponents, a defender for the championship), they should take a rest to make self-examination to know why. For example, Mary Pierce lost in first round of three tournaments consecutively since she lost to Li Na in third round of US Open at three ago after. When she won the first set 6-4, and then she lost twice set 0-6 suddenly. Since she won the first set, she should win the second set to face against the eventual champion Maria Sharapova. :angry: What do you think?
