I have just watched CM vs Okuhara. Beside her very bad court manners, CM did strike me has a one dimension player in this match. She just could not try to do something else then what she normally do. Very stubborn. (Okuhara as well, though it was working for her!)
In fact it was GC who first pointed out that even Intanon Ratchanok is learning to scream like Marin upon winning a point. Forgot which recent tournament she was referring to, may be the HK Open.
