What it is
Shaping a pitch with data instead of feel
Every pitch leaves a fingerprint: how fast it spins, which way the spin is pointed, how much of that spin turns into movement, and where it comes out of the hand. Trackman measures all of it on every throw. A high speed camera shows what the fingers are doing at release, which is the part nobody can see live. Put those together and a grip change stops being a hunch and becomes something you can check on the very next pitch.
