“You had to throw it down Broadway to get the call.”
What this shows — how Nick Mahrley called the 180 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 163 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 · 3 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1William Contreras — ump said ball, robot ruled strike: overturned.
- 2Pete Crow-Armstrong — ump said strike, robot ruled strike: upheld.
- 3William Contreras — ump said ball, robot ruled strike: overturned.
- 4Christian Yelich — ump said strike, robot ruled ball: overturned.
- 5Matt Shaw — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 5 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
