Home plate: Louie Krupa
“The kind of night where the umpire is the least of the story.”
What this shows — how Louie Krupa called the 139 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 130 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

ABS — the Automated Ball-Strike System
3 pitches went to the robots · 1 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Jake Rogers — ump said ball, robot ruled strike: overturned.
- 2Eduardo Valencia — ump said strike, robot ruled strike: upheld.
- 3Eduardo Valencia — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 3 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
