Watching her play isn't good for my heart; she plays such a pleasant game, but she's incredibly frustrating to watch. She's on a razor's edge; to me, she lacks some bread-and-butter strokes/patterns that she can rely on when things get tight. When she plays well she really does; but when she's slightly below par, she really loses points, games or sets by the fistful. And that, even when things seem to be going her way during a match. For an attacking player, her serve+1 isn't good enough to allow her to close in on her own terms reliably. Despite having a fairly tall build, she has a power deficit from the baseline. She has good footwork technically speaking, but she isn't the fastest either, so that compounds on the return of serve and when rallies get going where a powerful opponent can just hit through her.
It's still possible since she made the quarters at the USO after a frankly dreadful slam run last season (I suffered through that match against Park, that was woeful), but I wouldn't favour her against basically anyone. Even in that match against Osaka she had opportunities that she couldn't convert; she doesn't have safe and reliable plays at all. I wonder if she forced herself to play, because her level was incredibly low during the first part of the season.
