“Quietly excellent. The best umpiring is the kind you forget was there.”
What this shows — how Erich Bacchus called the 157 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 151 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

Run impact from the count run-value table: a missed strike three is worth far more than one on 3-0.
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.
- 1Harry Ford — ump said ball, robot ruled ball: upheld.
- 2Jorbit Vivas — ump said strike, robot ruled ball: overturned.
- 3Joe Mack — ump said ball, robot ruled strike: 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.
