There is really a huge disparity between Serena and everyone else. I think this is because of the inability of the women to generate enough pace on their shots. If you look at men's matches alongside the women's, you'll see that the men hit their groundstrokes with noticeably more pace than the women, with the consequence being that it is more difficult to hit through a good defense or produce a clean winner. And since Serena has such good defenses, it is more difficult for any woman, even the tops ones, to put her on the defensive than it is for a top guy to do the same to someone like Djokovic.

In other words, Maria brought a Humvee to a tank fight.
