SoCal ProCase Trackman Files: Fastball

Pitchers were able to throw in simulated outings during gameplay and were able to get numbers and metrics off of our Trackman unit, such as pitch velocity, spin rate, horizontal & vertical movement & much more. There were some players who showed up and continued to build off of prior performances, but there were also some new names who jumped onto our radar with a strong showing.

Max Fastball Velocity: This metric calculates the speed of the pitch as it’s released from the pitcher’s hand.

Fastball Spin Rate: This metric calculates the rate of spin on the baseball as it leaves the pitcher’s hand, measured in revolutions per minute (rpm). Historical data shows that high-spin fastballs lessen the impact of gravity, allowing for more ‘rise’ (or less fall, in other words) as it carries through the zone. Low-spin fastballs typically indicate the pitch has greater horizontal action, often making it tougher to square up, but generally easier to make contact with, leading to more ground balls, while high-spin fastballs show a correlation with swings and misses.

Fastball Horizontal Break: Horizontal movement is measured in inches between where the pitch actually crosses the front of home plate side-wise, and where it would have crossed home plate side-wise if had it traveled in a perfectly straight line from release. A positive number means the break was to the right from the pitcher’s perspective, while a negative number means the break was to the left from the pitcher’s perspective.
