Movement Profile (Induced Break)

Pitching+ by Pitch TypeThe overall grade and per-pitch grades are rescaled independently against different populations. Per-pitch grades compare a pitcher's sinker to all sinkers, slider to all sliders, etc. The overall grade compares a pitcher's total pitch mix against all pitchers. Because averaging across pitch types reduces variance, the overall population is tighter — so the same raw advantage gets amplified more. A pitcher who is consistently above average on every pitch will have an overall grade higher than any individual pitch grade.
