Hi, I'm currently a Junior in Southern California. And I'm really interested in playing college tennis. But I have some questions: 1) I want to know what USTA national/sectional rankings you need to have to play for DI, DII, DIII colleges. 2) If a coach in a certain college wants you, can that coach guarantee your chances of getting into that college (or can the coach backstab you at the end)? any help would be nice and thank youuu!!!
