Baseball is often credited with being the first major sport in the US to fully embrace advanced data and metrics. The “Moneyball” revolution was carried out in the pursuit of winning more games. The next breakthrough on the diamond may be leaning on advanced data and outsiders once again, but this time it will be carried out in the hopes of protecting players’ health.

Lance McCullers to undergo Tommy John surgery and to miss 2019 season. What caused his injury, workload or mechanics? Could it have been prevented? His shoulder, trunk, lead foot and lead knee mechanics are pretty sound. Unfortunately, his workload profiles are abnormal for the year. A month off in August caused his chronic workload to drop significantly. Late September and Postseason outings were low in volume as a reliever (11-16 pitches per outing). Even these short outings led to high AC Ratios. His last outing he threw 33 pitches resulting in an AC Ratio of 1.9. The math shows he should have stopped at 15 pitches to keep the AC Ratio under 1.3- a known safe limit. IT TAKES TIME TO BUILD CHRONIC WORKLOAD. DONT GUESS WHEN YOUR ARM IS READY OR HOW LONG YOUR OUTINGS SHOULD BE.

In this episode of Sideline Data, we’ll examine how arm sleeves like the motusTHROW have the potential to shape the future of pitching. To understand the performance and medical benefits of this MLB-approved device we sat down with Dr. Joshua Dines.
