Firstly congrats your season and exceeding your own expectations in your throwing recently. It’s great to hear about your success from hard work and dedication. As a lefty in high school throwing in the 80s is very good, and being able to sit in the low 80s every time is even better. Especially as a freshman. All I can say here is keep busting it and working to stay healthy and get better but your velo is definitely there. so don’t overtrain yourself and cause an injury just trying to throw faster. Even now as a freshman in the low 80s from the left side, with a strong off speed and decent curve, you could have options at every level of college. It honestly comes down to the quality of your off speed and being a good pitcher instead of just a hard thrower. A lefty from my high school just went juco and was throwing mid to upper 80s due to the fact that he was a raw athlete, but his pitching wasn’t at the level of guys going D2 and D1. Keep working hard but don’t let velo be the only goal youre chasing. Continue to develop as an all around pitcher and you can have a very bright future.
