Andres Munoz has a bit unconventional mechanics for a 104 mph thrower, but take note of what he still does very well. His initial weight shift (the ‘drift’) shifts his center of mass away from the rubber and pre loads the back hip.
From there, the outer glute drives him effortlessly into hip Abduction which creates a turbo boost effect and unwinds the spiral of energy up through his body.
Watch the arm loosely relax into layback and whip through at the last second. Does he have genetic factors at play here? (Fiber type, limb lengths, etc). Yes. But he’s still doing the fundamentals of elite throwing and energy transfer very well.
