Home plate: Louie Krupa
“Down the middle. Both dugouts had the same zone.”
What this shows — how Louie Krupa called the 159 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 148 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 · 3 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Drew Cavanaugh — ump said ball, robot ruled strike: overturned.
- 2Mookie Betts — ump said strike, robot ruled ball: overturned.
- 3Will Smith — ump said ball, robot ruled ball: upheld.
- 4Josue De Paula — ump said strike, robot ruled ball: 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.
