Pitch tempo measures the median time between pitches (in other words pitch release to pitch release). Only pitches that follow a take (called strike or called ball) and are thrown to the same batter are considered for this metric. Note: This metric is updated weekly.
For added context we label any pitch thrown within 15 seconds to be "Fast" and any pitch thrown after longer than 30 seconds to be "Slow".
Before you compare this metric to the newly approved 2023 pitch timer please note that this is not measuring the same timing as the MLB pitch timer.
