Today we’re joined by Will Carroll, nationally recognized injury expert and author of Under the Knife. Known for translating complex medical data into clear, actionable insight, Will brings a unique perspective on baseball’s evolving injury landscape and what he famously calls the game’s “billion-dollar bleed.”

We dive into the financial and competitive impact of injuries across Major League Baseball, the data trends shaping modern sports medicine, and how teams can better measure and manage injury risk. Will shares his thoughts on workload, UCL injuries, biomechanics, recovery science, and how communication between athletic trainers, physicians, front offices, and analysts has changed over time.

This episode offers a candid look at the intersection of medicine, performance, and economics, breaking down what the injury numbers really mean for clubs, players, and the future of the game.
