What this shows — how John Libka called the 130 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 121 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 · 3 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Willson Contreras — ump said strike, robot ruled ball: overturned.
- 2Mickey Gasper — ump said ball, robot ruled strike: overturned.
- 3Ceddanne Rafaela — ump said strike, robot ruled strike: upheld.
- 4Nick Fortes — ump said strike, robot ruled ball: overturned.
- 5Chandler Simpson — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 4 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
