Best-in-class tech measuring what matters
The technology behind your BASE results, visible in Stacks and the MLBU app.
Speed
Breakaway
Captures running performance metrics such as top speed in the acceleration and sprinting phases of a 20-yard sprint.
Power
Loden
Measures jump performance metrics such as height, power, and Reactive Strength Index.
Hitting / Pitching
Trackman
Tracks ball flight data including spin and angles for all players, plus movement and velocities for pitchers and exit velocities for hitters.
Swing Tech
Diamond Kinetics
Analyzes the swing metrics including bat speed, attack angle, and bat path.
Biomechanics
Uplift
Evaluates pitching and hitting biomechanics to show how well players sequence their movements and their overall efficiency.
Your data, two ways to see it
BASE results live in Stacks, a personalized dashboard where athletes access in-depth analysis and share their profile with instructors, coaches, and scouts. BASE data is also available in the MLB Universe app, MLB's free app — currently in early access — for athletes and families to track their game, earn rewards, and stay connected to the game they love.
