For an introduction: I’m a D3 LHP, I’m 6’4, 200lbs. Last year was my first year with my team and I didn’t get any innings because of control issues. Currently I throw 83-85, but almost all my power comes from my arm and front oblique muscles pulling. This offseason I’m trying to work on my mechanics to actually use my lower half so I can be quieter with my front side and arm (I have a wonky arm action as is). I also want to be able to actually use my body, because I know I have the strength and flexibility to throw significantly harder than I do now with less stress on my arm. Over the past few weeks I’ve been looking into mechanics for the first time in my life and doing dry work to try and implement these into my throwing. Specifically, I decided to start from the ground up to try and fix my mechanics. Right now, I’m having a lot of trouble getting a feel for everything, and I’m very front leg dominant. I feel like a get to a decent loaded position, but as soon as my lift leg starts to move forward I immediately rush it forwards and open my hips, my back foot loses contact with the rubber, and all my weight crashes onto my front leg about 4 inches to the left of my back foot. Meanwhile, my back leg extends too early and then drags behind my hips until release, where my upper half torque pulls it up and around. All of this is preventing from generating any hip to shoulder separation and external rotation in my arm action. What can I do to stop being so front half dominant, hold torsion and get to a better loaded position?
