Today Novak Djokovic beat Rafael Nadal in one of the greatest tennis matches of all time. The third set alone lasted over one and a half hours. This was not a match that involved pitty pat points. Every point was full out shots from both sides and in the end Djoovich was able to pull it out

Just to be clear, I have watched many matches that went on for hours but this is the only one I have seen that involved the participants going all out on every point.
