Pitch familiarity
Pitchers' arsenals are grouped by pitch shape — velocity, break and spin — and weighted by how often this pitcher throws each, so the number describes the arsenal he will face tonight.
Compared against this batter's own mark across every shape he has faced, so “done well” means well for him.
Descriptive — the model does not read it.

How Semien, Marcus handles each pitch
Reading these bars
One row per pitch this pitcher throws, ordered by usage. The bar is how this batter has performed against it; the dotted line is his own average from that hand.
Deeper red is better than his usual, deeper blue worse.
Faded rows have too little contact to trust — the count on the right is the sample behind the number.

King, Michael's Arsenal, by Pitch Type
ordered by usage vs. a RHH batter
Matched by pitch name
Left: what the pitcher throws. Right: how this batter has done against that same pitch.
The right-hand columns count only pitches carrying the same label — a slider against a slider — thrown by pitchers with the same handedness.
That is precise but can leave a small sample. The table below groups by how a pitch actually moves instead.

King, Michael's Arsenal, by Pitch Shape
grouped by velo/break/spin, not label
Why shape beats the label
The table above, grouped by how the pitch moves rather than what it is called.
Two pitchers can both say “slider” and throw very different pitches. Grouping by speed, break and spin pools everyone throwing something physically similar, so the sample is bigger and steadier.

Every plate appearance
One row per plate appearance, newest first. Strikeouts and walks included.
Expected stats say what a batted ball was worth given how hard and at what angle it was hit, whether or not it found a glove.
xBA is blank on strikeouts and walks — there is no batted ball to judge. xwOBA counts them.
