BOS @ KC
Home plate: Erich Bacchus
“A workmanlike night — nothing to frame, nothing to fix.”
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.
The zone, as he called it
The calls that moved the game
- 1-0.30▲4 · 3-1 ball called strike
Nick Sogard vs Michael Wacha - 2-0.13▼8 · 1-1 ball called strike
Jac Caglianone vs Jovani Morán - 3-0.09▲2 · 0-0 ball called strike
Isiah Kiner-Falefa vs Michael Wacha
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
2 pitches went to the robots · 1 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Carlos Narváez — ump said ball, robot ruled strike: overturned.
- 2Nick Sogard — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 2 of 2 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
