Pitch Sequencing
How to read this figure
Each cell is P(next pitch type given the previous pitch type) within one plate appearance, one matrix per count-leverage class. Rows sum to at most 1; the remainder is next-pitch types off the top-8 axis.

Open the interactive inspector: Pitch sequencingWhat it means
Pitch selection is sticky, and stickiest exactly when the pitcher must throw a strike. When ahead the FF-to-FF repeat drops to 39.44% and the mix diversifies. Off-speed pitches self-repeat too, a slider follows a slider 35.35% of the time across all counts.
Caveats and confounds
Descriptive only; strict pitch-number adjacency within a plate appearance; pitch_type is Statcast's auto-classified code. It reports observed sequencing rather than a forecast.
