Sequencing is the key to the pitching delivery. To help you more clearly visualize what the kinematic sequence looks like, we have added sequencing charts to the Mustard app.

There are three things that contribute to keeping a pitcher’s arm healthy: Workload, biomechanical efficiency, and functional strength. Of those three things, the one parents, coaches and athletes can all easily do is count pitches.

Throwing is not the best warmup for throwing! Learn how to properly warm up with coach Tom House's science-based training program.

Kids need to learn basic catching and throwing skills before they should even think about learning to pitch. The process of growing up as an athlete is much more enjoyable for both kids and parents if you move at an age-appropriate pace and take pleasure in small gains.

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.

The ability to store torque in the pitching delivery is responsible for up to 80% of velocity.

As a pitcher’s shoulders begin to square up toward home plate, the glove needs to swivel so the palm is facing the chest and stabilize over the landing foot, inside the width of the torso, between the shoulders and the belly button.

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.

Set position determines all of the balance and posture positions that are necessary to initiate the delivery.

Head position is incredibly important in the pitching delivery. If your head moves too much, you’ll first have difficulty throwing strikes, and you’ll eventually run the risk of injuries from the excessive stress.

Proper grip and wrist and forearm position can help young pitchers prevent injury and increase both velocity and movement.

By Lindsay Berra Eddie McCartney’s journey to Mustard began in a batting cage rather than on a pitcher’s mound. Eddie was 9 years old, and he was afraid of the ball.

When done properly, even a pre-adolescent can use weighted balls to build strength and speed in the pitching delivery.
