If she can play consistently like she did today, definitely top 50. Maybe even more i she can get very tough and confident mentally. She has a huge forehand, an above-average first and second serve, a quality volley, great movement, and that slice backhand can be so biting it could give most of the girls on tour trouble.
However, I don't think her long forehand stroke and her backhand slice will hold up well against the top 15 players. She could make top 30 if she really stays focussed and gets more confident.
