How he throws 94mph
behind the scenes
Clay’s jump in velocity wasn’t random. It came from building his engine and learning how to actually use it.
Three months ago, Clay was an upper 80s arm, occasionally touching 90 to 91 mph. Today, he sits 90 to 91 and has reached 94 mph. The difference was not just strength. It was his ability to produce and transfer force efficiently.
Early on, Clay already had solid physical tools. He was strong for his size, lean, and naturally athletic. But none of it showed up on the mound. His delivery was stiff and disconnected. His spine stayed stuck, his movements were choppy, and there was no real flow of energy from the ground up. He had horsepower, but no engine.
The first priority was building that engine.
This meant training for concentric impulse and rate of force development. He needed to create force quickly and repeat it pitch after pitch. Instead of slow generic lifting, his program emphasized explosive intent, short duration high output sets, and movement in all three planes. The goal was not just getting stronger, but learning how to express that strength.
At the same time, his mechanics were simplified so that force could actually transfer. By shortening his stride and reducing unnecessary length in his delivery, he created a more efficient window to accelerate. This allowed his body to move freely instead of fighting itself.
Once that clicked, everything changed.
His average velocity increased. His peak velocity jumped. More importantly, his consistency improved and he stopped dropping into the mid 80s late in outings.
