I’ll watch two club players during a point and suddenly one of them will try and end it when they had no advantage, no opening, no reason to do so. They just got impatient. Lendl in the ’80s knew when to strike. He was patient. In fact, one of the reasons his game has suffered in the ’90s is that he isn’t as patient as he used to be. Maybe he just can’t wait to get home to his family, but he definitely doesn’t have the patience that he used to possess.
