“An honest evening's grade: nothing loud, nothing missed by much.”
What this shows — how Erich Bacchus called the 220 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 204 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+0.30▲5 · 3-1 strike called ball
Gleyber Torres vs Kyle Nicolas - 2+0.28▲7 · 1-2 strike called ball
Gleyber Torres vs Brock Burke - 3+0.21▼7 · 3-0 strike called ball
Dane Myers vs Will Vest
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 · 2 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Sal Stewart — ump said strike, robot ruled ball: overturned.
- 2Ke'Bryan Hayes — ump said strike, robot ruled strike: upheld.
- 3Dane Myers — ump said strike, robot ruled strike: upheld.
- 4Dillon Dingler — ump said ball, robot ruled strike: overturned.
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.
