Home plate: Willie Traynor
“The zone shrank when the pitchers needed it most.”
What this shows — how Willie Traynor called the 143 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 130 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

Run impact from the count run-value table: a missed strike three is worth far more than one on 3-0.
ABS — the Automated Ball-Strike System
5 pitches went to the robots · 2 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Luis Campusano — ump said ball, robot ruled strike: overturned.
- 2Xander Bogaerts — ump said strike, robot ruled strike: upheld.
- 3Luis Campusano — ump said ball, robot ruled ball: upheld.
- 4Gabriel Moreno — ump said ball, robot ruled strike: overturned.
- 5Gabriel Moreno — 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.
