The Relationship Between Pitching Velocity and Injury Risk

This chapter discusses the correlation between pitching velocity and injury risk, noting that players with higher fastball velocities are more likely to experience ligamentous injuries and require surgery. It highlights the increase in UCL surgeries over the years and the greater vulnerability of pitchers who experience a sudden increase in velocity or transition to the bullpen. The chapter also explores the downstream effects of increased pitching velocity, including changes in hitter training, hitter-catcher interactions, and the rise in pitcher injuries caused by line drives and ground balls.
