About All These Velocity Spikes

This year, however, with Statcast officially replacing PITCHF/x in the big leagues, the data being pulled publicly is now from the Trackman radar. While PITCHF/x velocity numbers were reported at a defined point along each pitch’s trajectory — usually at the 55 foot mark — so that velocity didn’t have to be calculated at every x/y point along the pitches path, Statcast outputs the highest velocity that Trackman records along the flight of the pitch, which due to physics, is going to be immediately after the ball leaves the pitcher’s hand.

So what the broadcasters have said is true; MLB is essentially measuring velocity out of the hand this year, while the publicly collected data from prior years was measuring velocity at a point a few feet closer to the plate, so the readings showing up on TV and on FanGraphs in 2017 will be higher than they were in the past. But this wasn’t MLB moving the point at which they were measuring velocity; this was just the result of switching from PITCHF/x to Trackman, and the different outputs from a camera-based system to a radar-based system. If you compare Statcast velocity from last year to Statcast velocity from this year, you can get around this systematic shift, and more easily compare apples to apples.
