That was a first.
On first point at 5-6, Nole reaches over net to strike ball. Murray watches the point on replay and sees that Djokovic was over the net. Murray says, that's my point! Murray and Djokovic meet at the net. Nole pats Murray on the arm and says he hit the ball AFTER it went over the net. Chair says Nole was level, not over, point Nole.
Andy's rattled and loses game at love.
Just so you know, Andy's ball had no chance of clearing the net in the first place. It was poorly stuck and lobbish, dropping out of the sky. If Nole let it go, he would have won the point. Technically, Murray's point, but kind of a weak point to lose your mind over.
