Wozniacki has magnificent shotmaking if you ask me, but it's not the power kind of one. She has to rely on all court tactics to make effective her sweet topspin mix, while still able to hit pretty decent winners when she feels them, especially with the backhand. Despite not making many winners, she's still an agressive baseliner, and she doesn't only win matches by waiting the opponent's mistake, though she can do that at times also.
Expected. Piter is one of the worst players who have ever entered Top 100, I guess, at least of recent history.
No need to overrate this win keeping in mind that she already had some bigger wins last year on Hard Court. She should really try to get her ranking up by these ITFs first, instead of trying to qualify for every single WTA tournament.
