Cory Ann is def a good player. She hits the ball with two hands on both sides and has a personality sort of a like bunny on amphetamine. She's always pounding her thigh with her fist, jumping up and down, encouraging herself after every shot. She is hands down the biggest fighter on tour, even more than Monica!!! I've seen her play 5 times and she only played well once, yet manged to push into a third set or even win the match out of sheer will. She often will come back from 5-1 or 5-2 and even if she doesnt win the set, she'll at least make it a 6-4 set. She's also a real sweetheart too.
She'll surely make top 100, maybe top 50, but unfortunately I don't see top 30. Her problem is that she is soooo streaky. It's almost impossible for her to string 2-3 solid matches in a row. Her serve is absolutely awful too. It clicks one match out of 4, other than that her first serve % is about 40. When her first serve goes on it's very solid, but her toss is all over the place so she never gets a consistent motion. She also kind of rides the emotional roller coaster a bit. She'll be all jazzed up one game and then sulking and throwing her racket the next. EVERY match I've seen her lose she has been in tears after.
So to answer your question, she'll probably have a career that involves a couple of WTA semifinals, maybe one final at the lower level, a match at a GS where she either scalps a top 10 player or pushes a top 5 player to a very close 3 setter, and will probably peak at around 40
