Location sequence
Type plus a 4-region plate map (up-in, up-away, down-in, down-away). Pairs under 20 sequences are hidden. Count filters do not apply here.
No location sequences for this player-season yet.
Transition flow
Two-pitch sequences. Link width is how often the next type follows.
Transition lift
P(next | first) minus the unconditional next-pitch mix. Positive means that follow-up is used more than usual after the first type.
Sequence tree from Four-seam Fastball
Branches are 2-pitch, then 3- and 4-pitch n-grams when the sample clears the display floor. Count filters hide 3/4-grams.
Chase% after Four-seam Fastball
Last-pitch rates on the follow-up. Sample floors hide tiny pairs.
Pooled model after Four-seam Fastball
Observed mix versus a league-pooled next-pitch model given last pitch and count. Smoothing for rare contexts, not a sit or pick.
