“Down the middle. Both dugouts had the same zone.”
What this shows — how Alfonso Márquez called the 166 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 154 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

ABS — the Automated Ball-Strike System
4 pitches went to the robots · 2 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Gabriel Moreno — ump said strike, robot ruled ball: overturned.
- 2Gabriel Moreno — ump said ball, robot ruled ball: upheld.
- 3Jordan Walker — ump said ball, robot ruled strike: overturned.
- 4Masyn Winn — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 1 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
