I’m currently a 5’10 175lb high school sophomore. One of my goals heading into the summer was to hit 80 mph. So far, the hardest I’ve been gunned at is 78mph (whilst consistently sitting low 70s). As a high school pitcher, this obviously isn’t enough to survive. Hence, one of my reasons to work at increasing velocity. I’m able to long toss across the foul lines (which is roughly 300 feet at my field). According to some tables, that should correlate to mid 80s velocity, but that isn’t quite the case.
Furthermore, I’ve had major command and control issues. My coach has noted that it’s an issue with release points and consistency. However, with the number of kids that he has to look out for, it’s really hard to find time adjust things with the coach.
I’ve attempted to fix my own mechanics the past few weeks for several reasons. I’ve heard that I had “flat arm syndrome” (arm parallel to ground at foot strike), I want to load earlier and lastly increase velocity. So, I started trying out 90-degree separation in order to address these issues. Attached below are videos pre and post “mechanical adjustment”. I slowed it to 10% the second time around and froze the frame during footstrike.
Apologies for no side view.
However, it seems like having this type of 90 degree separation has created really long arm action. I’ve heard having a long arm action is actually really bad for both health and consistency. I’d go from 78 on one pitch to 69 the next at times.
What should I do to improve my mechanics and throw harder? It obviously looks like a mechanical issue, so any comments that relate to that (opening too early, not using legs enough, etc)? Were my mechanics better before or after the adjustment?
Thanks very much.
