“An honest evening's grade: nothing loud, nothing missed by much.”
What this shows — how John Libka called the 143 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 135 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
3 pitches went to the robots · 2 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1William Contreras — ump said ball, robot ruled strike: overturned.
- 2Rafael Flores Jr. — ump said ball, robot ruled ball: upheld.
- 3Brice Turang — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 2 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
