Things got tense inside Arthur Ashe Stadium tonight as Serena Williams lost control after having a foot fault called on a second serve to give Kim Clijsters a match point. Serena's obscenity-laced tirade directed at the lineswoman resulted in a point penalty, which gave the win to Clijsters. It was a tough situation, and probably a bad call, but Serena's conduct was inexcusable in this case.
