WHAT IS DVS?

DVS, which stands for Delivery Value System, is a bio-mechanical based model that is statistically proven to predict the relative risk associated with any pitcher’s delivery. 

WHEN Was DVS CREATED?

The name Delivery Value System and the concept of the DVS Scoring System were initially outlined in December 2012.  The current DVS Model (Scoring System + Statistical Model) became official in January 2014 and has remained unchanged since that time. 

WHY WAS DVS CREATED?

The Delivery Value System was created in light of the current epidemic of throwing-related injuries in the game of baseball.  The surgery rate among pitchers has continued to rise over the past several years due to various culture-related factors, including an increased emphasis on throwing velocity, college scholarships, and year-round playing.  Among these, a pitcher’s mechanical pattern plays a vital role in either placing more or less stress on a pitcher’s throwing arm.  Therefore, the DVS serves to find injurious patterns within any pitcher’s delivery, and then objectively correlate those patterns with overall injury risk.  By attaching a numerical value to a pitcher’s specific mechanical pattern as it relates to injury, this objective approach removes the subjectivity associated with any one style, methodology or training system. 

The Delivery Value System aims to create an international database of DVS scores to enhance the accuracy of the model and strive towards reducing the number of throwing-related injuries on a global scale.  We want DVS to be a resource for all players, coaches, teams, organizations, and medical professionals.  By educating and linking in all channels within the game of baseball, we can help foster an environment of injury awareness better than what currently exists. 

Overall, our goal at DVS is to positively influence the next generation of youth baseball players, which will have a dramatic impact on the game of baseball in years to come

HOW WAS DVS CREATED?

In an effort to find answers as to why some pitchers get hurt and some pitchers don’t, we started analyzing video and breaking down various mechanical patterns from past and current players. Through this analysis, we started to notice similarities between players that were able to throw for longer periods of time without sustaining a throwing related injury. 

In order to see if these patterns were relevant to a pitcher’s health and performance, we created a teaching methodology that was tested on a daily client-base over a several year period at Baseball Rebellion in Durham, North Carolina.  After observing anecdotal improvements in both health and performance over a two year period, we decided to formulate a formal scoring system based on the patterns found in elite level pitchers that had a low onset of injury. 

After seeing pattern relevance in both elite and youth level pitchers, we decided to outline a formal study  to determine if the DVS Scoring System was statistically relevant at predicting throwing related injuries.  After significance had been determined using a survival analysis model called a Cox Proportional Hazard Model, Delivery Value System, LLC was officially formed.
