Controlled Tempo: The pitcher maintains a consistent and controlled tempo in the initial phases of the delivery, including a balanced leg lift, which provides a solid foundation to build upon.
Severe Lateral Trunk Tilt: The most critical issue is the excessive side-bend towards the glove side. This compromises posture, reduces power, hinders command, and places undue stress on the arm.
Inefficient Sequencing & Separation: The upper and lower halves rotate almost as a single unit (‘opening early’). This lack of separation between the hips and shoulders significantly reduces the ability to store and release rotational energy, limiting velocity.
Late Arm Action: At front foot strike, the throwing arm is not in an optimal position (‘up’). This ‘arm drag’ forces the arm to violently ‘catch up’ to the body, increasing injury risk and decreasing efficiency.
Front Leg Instability: The front knee remains bent at ball release and does not brace effectively. This ‘soft’ front side absorbs energy that should be transferred up the kinetic chain and into the baseball.
