“An honest evening's grade: nothing loud, nothing missed by much.”
What this shows — how Erich Bacchus called the 160 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 150 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.
The zone, as he called it
The calls that moved the game
- 1+0.39▼3 · 2-2 strike called ball· challenged

Alex Bregman vs Nick Pivetta - 3-0.13▲1 · 1-1 ball called strike
Michael Busch vs Nick Pivetta
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
4 pitches went to the robots · 1 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Pete Crow-Armstrong — ump said strike, robot ruled strike: upheld.
- 2Ethan Salas — ump said ball, robot ruled strike: overturned.
- 3Ethan Salas — ump said ball, robot ruled ball: upheld.
- 4Carson Kelly — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 3 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
