“An honest evening's grade: nothing loud, nothing missed by much.”
What this shows — how Chris Conroy called the 235 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 221 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.
- 1Munetaka Murakami — ump said strike, robot ruled strike: upheld.
- 2Connor Wong — ump said ball, robot ruled strike: overturned.
- 3Miguel Vargas — ump said strike, robot ruled strike: upheld.
- 4Caleb Durbin — ump said strike, robot ruled ball: overturned.
- 5Drew Romo — ump said ball, robot ruled strike: overturned.
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.
