If you’re a professional performance coach, hitting coordinator, or biomechanics professional, you’ve likely heard about markerless bat tracking. This Q&A covers how it works, what’s required to run it, and the key questions performance staff are asking.

Driveline set out to capture bat speed, bat path, and full-body mechanics at the same scale and intensity as their everyday training. With Theia3D’s markerless bat tracking, they now collect synchronized bat-and-body data from real swings—no sensors, no added workflow, no slowdown. The result is deeper swing diagnostics delivered at true Driveline volume, giving coaches clearer feedback and athletes more actionable development.

The PLNU × Padres Biomechanics Lab set out to measure swings the way athletes actually perform them—at full intent, in real training environments. With Theia3D, the team now captures synchronized bat and body mechanics without markers, sensors, or workflow disruption. Early results reveal what game-speed swings truly look like and why this shift is reshaping both research and player development.
