ATL @ MIA
Home plate: Alfonso Márquez
“Solid and unspectacular — exactly what the job asks.”
What this shows — how Alfonso Márquez called the 168 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 160 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 · 3 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Drake Baldwin — ump said ball, robot ruled strike: overturned.
- 2Joe Mack — ump said ball, robot ruled strike: overturned.
- 3Joe Mack — ump said ball, robot ruled strike: overturned.
- 4Joe Mack — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 4 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
