Something like this.....
Some probably consider it a compliment to be at or near the top of the list and an insult to be in the lower regions, but I don't think that either one is true.
Well, like it or not, but the top four players in your list have won 21 slams and 5 YECs (combined).
The bottom four players of your list have won ZERO slams and ZERO year-end-championships.
Experience is telling us that players who are labelled by some as brainless ballbashers like Li and Petra can once in a while (two weeks is enough
) keep their shots between the lines and win a slam.
[ballbashers - aggressors]
kvitova, li, masha, stosur
[pusher - defenders]
aga, errani, woz
Great way to look at it, I agree, although there are obviously some notable differences within individual groups.
