Ash Barty is looking impressive. I'd peg her to have a Henin-type career.
Okay, it's a slow night. I'll bite. But I will preface my comments by saying that I think your post is tongue in cheek because the knuckleheads on ESPN is tripping all over themselves to wind up the hype machine around this girl and set it on its way.
That being said, I will build a shrine of solid gold in your honor if this girl has a Henin-type career. At her size, she's got to be faster and be able to win points from anywhere on the court. I'd peg her to have a Cibulkova-type career, and there's nothing wrong with that. Cibulkova is a solid, Top 20 player. And if she's better than Cibulkova, her max is Kerber.
By contrast, Henin was winning slams and ranked #1 in the heyday of women's tennis against the likes of Serena, Venus, Kim, Maria and the Russians, and Capriati. Even against today's crap crop of crap, this girl won't standout.
EDIT: In fact, I know she won't amount to diddly-poo: she's not even on Chris's list of girls to watch.
