“If it was close, it was a strike. The hitters noticed.”
What this shows — how Alfonso Márquez called the 123 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 115 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
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.
- 1Eduardo Rodriguez — ump said strike, robot ruled ball: overturned.
- 2Seiya Suzuki — ump said ball, robot ruled strike: overturned.
- 3Alex Bregman — ump said strike, robot ruled strike: upheld.
- 4James McCann — ump said ball, robot ruled ball: upheld.
- 5Ian Happ — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 3 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
