How exactly do you quantify the heat of the moment? Isn't being involved in a match, considered the heat of the moment in general, when you're competitive juices are firing on all cylinders? We need to clear something up here, Novak was getting distracted by about two obnoxious fans from the first set, you can see at first he was being very silent but giving them stares, as if saying to stop it....but they kept at it, so naturally when you have so much on the line, you think you will allow some moron from the crowd try to impact that? The umpire should have stepped in, and you know this, if he could hear on the actual court, she can clearly hear it, and she finally did, but that was when it was the third set.
Tell me, is this the heat of the moment?
