The PITCHf/x system, first used in the 2006 MLB postseason, is a camera-based system that can measure the trajectory, speed, spin, break, and location of a pitched ball. This provides objective data that can be used in combination with statistical outcomes to better predict the effectiveness of a pitcher or batter. [ 4 ]
PITCHf/x is a system using three permanently mounted cameras in the stadium to track the speed and location of a pitched baseball from the pitcher's mound to home plate with an accuracy of better than one mile per hour and one inch. With PITCHf/x, statistics such as the pitcher with the fastest fastball, or the pitcher with the sharpest ...
A major league pitcher throws a baseball with a spin of around 20 rotations per second (rps). With each rotation, a four-seam fastball presents four seams crossing the vision of the batter, producing a flicker rate of 80 Hz, which results in the batter not perceiving any features on the ball and having fewer visual cues than with the two-seamer ...

Ford soon learned that by making a rough patch on one side of the ball, he could use the rough spot to get a firmer grip on the ball and increase the spin rate as he threw, making it harder to hit. [3] Ford first used the pitch in a game in 1909, hiding a piece of emery paper in his baseball glove. [4]

For most of baseball's history, there were no commonplace methods to quantify how hard-hit a batted ball was — the only aspect of the ball's speed being tracked was how fast the pitcher threw it, measured using various evolutions of radar guns. In 2015, MLB introduced Statcast technology to all 30 of its ballparks, in part to track exit velocity.
