To answer the OP's very general question with a very general answer, a 3.3 GPA and a 28 ACT or SAT equivalent. If you have outstanding baseball talent some HA D1's will go lower.
If you are an average baseball talent I would like to go to HF with a min 30 ACT and 3.5 GPA. HS course rigor is a whole different question, but HC's and RC's usually leave that up to admissions.
