Well, that&#x27;s a close explanation, except I think you&#x27;re confusing set and match. For men&#x27;s tennis, it takes 3 sets to win the match, with the potential of playing 5 sets.<p>I&#x27;m actually not sure that the math is true, though. (Or I really don&#x27;t understand what the stat is saying.) Let&#x27;s say that it actually is for every 4 serves, you win 3, Djokovic wins 1. That number gives you every game (winning the game game-point-15), to give you every set. I don&#x27;t see how Djokovic ever wins a game, let alone the set or match.
