At the @uspbl, this is how we begin to frame the process of increasing health/function to improve performance and spring training gives us a starting point. We collected 255 shoulder ROM tests across 40 pitchers. The clearest finding: 74.9% of tests showed a dominant-side shoulder flexion deficit. The average Flexion Diff was -4.7°. We also collected DVS metrics to understand delivery efficiency and arm injury risk. Average DVS Score: 12.9 / 24 8 of 39 pitchers scored 16 That tells us there is plenty of room for growth. This is the value of baselines. They give each pitcher a clearer understanding of where he is, what needs to improve, and how to take ownership of his development. Next week, the development system begins.
