AZ @ BOS
Home plate: Louie Krupa
“The strike zone picked a side, and wasn't shy about it.”
What this shows — how Louie Krupa called the 192 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 185 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
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.
- 1Gabriel Moreno — ump said ball, robot ruled ball: upheld.
- 2Caleb Durbin — ump said strike, robot ruled strike: upheld.
- 3Geraldo Perdomo — ump said strike, robot ruled strike: upheld.
- 4Nick Sogard — 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.
