“Tonight's zone had a rooting interest.”
What this shows — how Brian Walsh called the 128 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 116 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 · 3 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Ceddanne Rafaela — ump said strike, robot ruled ball: overturned.
- 2Connor Wong — ump said ball, robot ruled strike: overturned.
- 3Caleb Durbin — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 3 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
