Without doing the math - Djokovic is such a strong player that even if he's only returning a quarter of your serves, meaning you're 3/4's of the way to winning your set (I don't tennis, sorry if I'm getting the terms wrong), he's still probably going to beat you.
Well, that's a close explanation, except I think you're confusing set and match. For men's tennis, it takes 3 sets to win the match, with the potential of playing 5 sets.
I'm actually not sure that the math is true, though. (Or I really don't understand what the stat is saying.) Let'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't see how Djokovic ever wins a game, let alone the set or match.
It's hard to take any action based on that fact without further information. Even a gambler couldn't use that tidbit without conditioning on things like the current score. Or am I missing something?
