During the pitching delivery, a pitcher’s total body needs to get to the right place at the right time with the right sequence of movements. The Mustard app looks at all the biomechanical variables of the pitching delivery in a way that is much more accurate than the eyes could ever be.

In a pitching delivery, energy is transferred from the ground up, through the legs and into the torso. Up to 80 percent of that energy is then carried into velocity by angular torque. The final 20 percent of that energy is transferred through linear torque in the torso.

In just one year, with the help of coach Tom House and Mustard, pitcher Justin Courtney went from training solo in Maine to closing for the Los Angeles Angels Low-A affiliate, the Inland Empire 66ers.

The easiest way to ensure your biomechanical efficiency is to perfect your timing and stride.
