“Expanded the plate a touch past its 17 inches.”
What this shows — how Nick Mahrley called the 186 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 165 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
6 pitches went to the robots · 2 overturned (ump overruled) · 4 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Eliezer Alfonzo — ump said ball, robot ruled ball: upheld.
- 2Xander Bogaerts — ump said strike, robot ruled strike: upheld.
- 3Luis Campusano — ump said ball, robot ruled strike: overturned.
- 4Luis Campusano — ump said ball, robot ruled ball: upheld.
- 5Teoscar Hernández — ump said strike, robot ruled ball: overturned.
- 6Alex Freeland — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 5 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
