Brock Stewart, former Dodgers pitcher now with the Twins, saw a velocity spike after training, leading to Tommy John surgery. Despite past injury, he is now a successful reliever for the Twins.

The issue of pitching injuries in the majors continues to be a concern. Teams are seeking individualized injury prevention guidelines as high velocity is associated with success but also higher risk of injury. Dodgers and other teams are working on biomechanical data to better understand and prevent injuries.

The Dodgers paid more than $1 billion to injured players last season. Injury analytics expert Stan Conte is researching factors contributing to pitcher injury risk, but definitive answers are still elusive. Brock Stewart is assessed as having low overall risk.
