Your measurables are fine. But think of all the pitchers you’re up against with the same measurables and pitching experience. All you can do is hit remaining camps of targeted schools, go JuCo or play down.
The one thing about pitching is it doesn’t matter where (D1 or D3) a radar gun says 93 if you get there. It’s still 93. If you’re looking to get drafted someday most D3 players drafted are pitchers for the reason I stated.
