Summary & Recommendations

Primary Strengths

Athletic Foundation & Arm Speed: The pitcher possesses a strong, athletic build and demonstrates the ability to generate good arm speed despite mechanical inefficiencies. The arm action, in isolation, is fluid.

Initial Balance: Demonstrates good body control and balance at the peak of the leg lift, establishing a stable starting point for the delivery.

Primary Areas For Improvement

Lack of Hip/Shoulder Separation: This is the most critical area for improvement. The hips and shoulders rotate as one unit, which severely limits torque generation, reduces velocity potential, and places excessive strain on the arm.

Poor Arm Timing: At front foot landing, the throwing arm is not in an optimal, ‘scap-loaded’ position. This late arm action requires a violent acceleration to catch up, increasing the risk of elbow and shoulder injury.

Unstable Front Side: The glove side pulls early and the lead leg fails to brace firmly upon landing. This ‘soft front side’ causes a significant loss of energy and contributes to rotational instability.

Recommended Drills

1

Step-Back or 'Momentum' Throws

Purpose

To promote a more linear drive down the mound and improve the sequencing of the lower and upper half, helping the arm get on time.

Execution

Start with both feet at the back of the rubber. Take a step back with your throwing-side foot, then immediately drive forward into your throw. Focus on feeling your hips lead the way down the mound before your shoulders turn.

2

Torso Separation (Medicine Ball) Throws

Purpose

To train the feel of separating the hips from the shoulders to create elastic energy.

Execution

Stand sideways to a wall. Hold a light medicine ball (4-6 lbs) in front of your chest. Rotate your hips toward the wall while keeping your shoulders pointed forward, then explosively rotate and throw the ball against the wall. Focus on the stretch created across your core.

3

Lead Leg Bracing Drill

Purpose

To train the lead leg to absorb force and provide a firm post for the upper body to rotate against.

Execution

Perform a 'towel drill' (mimicking a full pitching motion with a towel instead of a ball). At front foot landing, consciously focus on planting the foot and firming up the quad and glute of the lead leg. Ensure the knee does not collapse or continue to flex forward as you rotate over it.
