Summary & Recommendations

Primary Strengths

Good Athletic Frame and Balance Point: At 6’0” and 176 lbs, the pitcher possesses a projectable frame for his age. He establishes a controlled and repeatable balance point at the peak of his leg lift, which provides a solid initial foundation for the delivery.

Primary Areas For Improvement

Lack of Hip-Shoulder Separation: The primary mechanical inefficiency is the simultaneous rotation of the hips and shoulders. This ‘rotational’ delivery limits the ability to store and release elastic energy, capping velocity potential and placing higher stress on the arm.

Inefficient Front Leg Action: The lead leg fails to brace or ‘post up’ at landing, remaining bent through release. This creates a significant energy leak, as the leg absorbs force that should be transferred up the kinetic chain to the ball.

Postural Instability and Glove Side Disruption: A pronounced lateral tilt and an aggressive pull of the glove-side arm cause the upper body to open prematurely and pull the pitcher off-line, negatively impacting both command and the efficiency of the arm’s path.

Recommended Drills

1

Step-Back or Separation Drill

Purpose

To create the feeling of leading the delivery with the hips while keeping the shoulders closed, thus improving hip/shoulder separation.

Execution

From the stretch, step backward with your pivot foot (right foot for RHP) behind the rubber. Then, initiate the motion by driving your hip toward the target while consciously keeping your chest and shoulders pointed toward third base (for RHP). Feel the ‘stretch’ across your core before unwinding to throw.

2

Lead Leg Post-Up Drill

Purpose

To train the front leg to accept force and stabilize, creating a firm block for energy transfer.

Execution

Perform a pitching motion without a ball, focusing solely on the landing. As the front foot strikes the ground, consciously straighten and firm up the knee, engaging the quad and glute. The goal is to stop forward momentum abruptly with the leg, forcing the upper body to rotate over a stable base. Hold the braced position for 2-3 seconds after the ‘release’.

3

Towel Drill with Glove-Side Focus

Purpose

To promote a more stable front side and prevent early shoulder rotation caused by pulling the glove.

Execution

Hold a towel instead of a ball. As you move through your delivery, focus on keeping your glove-side elbow pointed at the target for as long as possible before tucking it firmly against your torso. This prevents the ‘pull’ and helps keep the shoulders closed longer, which also improves head posture.
