OVERVIEW

Six mechanical component scores are summed together to produce an overall score, referred to as a DVS Score.  A DVS Score of a pitcher ranges from 0 to 24. As a pitcher's DVS Score increases, his risk of injury decreases.  A DVS Score not only gives a pitcher insight into injury risk, but when looking at the specific component scores of a pitcher, the entire risk profile is determined.  Two pitchers may have the exact same overall DVS Score, but may have entirely different risk profiles.  For instance, for every  component score increase in Mass & Momentum, a pitcher decreases their chance of injury by 17.5%.

 
 

DVS SCORING COMPONENTS

The six components which make up a pitcher's overall DVS Score are as follows.

  1. MASS AND MOMENTUM: measures is the positioning of the lower extremity as the front foot crosses the lead hip while the body moves down the mound.
  2. ARM SWING is the path of the throwing arm as it travels out of the glove to the point where the throwing hand extends above the throwing elbow.
  3. POSTURErelates to the positioning of the head and trunk as the body moves toward the target, before the front foot contacts ground.  
  4. POSITION AT FOOT STRIKE: is the positioning of the trunk and throwing extremity as the lead foot firmly plants against the ground.
  5. PATH OF ARM ACCELERATION: refers to the positioning of the arm during the late cocking phase of throwing into the point of ball release.
  6. FINISH: is defined by the transition of the pitcher’s body following release into a balanced follow-through position.
