I quit watching at 2-3 or something like that in the 3rd because of how absolutely mindless and sloppy Keys was. I thought I had poor rally tolerance. Holy bejeebies! Not only did she go for winners in at the worst possible points in a rally but she usually missed by exaggerated margins.
Still, when she plays well, her stroke is a thing of beauty and the power she generates is intense. If she can put it all together, she's going to be outstanding.
However, I'm shocked she won given that she appeared to be failing physically and mentally.
