So I am a 2017 LHP, and throughout the last few months I've made some pretty decent Velocity gains from where I was once was (used to throw unusually low, now pumping mid 70s and climbing I've put in tons of work to help change my mechanics, keep up with the lastest from Driveline, bands, weighted balls, etc. The product I've found to help the most was Austin Wasserman's HLT Throwing Patterns book! There's the good news.
Recently, our varsity pitching coach has begun to host small sessions of throwing after school. The first day I show up is back to "L-Drills" and the coach telling me I should now start throwing out of a very low arm slot (about as close to not submarining as you can get) for more "deception".
Some cues I've gotten so far:
Don't bring your arm down when you break, make a V and keep it there
First make the V, then an L
You don't throw hard, we all know that. So this will create deception (changing arm slot)
In the last week, the pain I used to have in my lower triceps from my freshman year has returned....coincidentally after I threw with him!
So as you can see, I'm a little frustrated. Even though our coach is a nice guy and pitched in the minors, I cant find the information he gives me helpful or useful. I don't know if I should just stop throwing with him, or try telling him what I think is best for me.
Any suggestions or advice would be appreciated.
