PIT @ STL
Home plate: Willie Traynor
“The zone shrank when the pitchers needed it most.”
What this shows — how Willie Traynor called the 168 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 152 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.
The zone, as he called it
The calls that moved the game

Spencer Horwitz vs Gordon Graceffo - 2-0.30▲2 · 3-1 ball called strike
Spencer Horwitz vs Matthew Liberatore - 3-0.30▲2 · 3-1 ball called strike
Nick Yorke vs Matthew Liberatore
Run impact from the count run-value table: a missed strike three is worth far more than one on 3-0.

- 5Ramón Urías — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 4 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
