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 131 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
- 1-0.13▲7 · 1-1 ball called strike
Braden Montgomery vs Kyle Finnegan - 2-0.13▲3 · 1-0 ball called strike
Chase Meidroth vs Troy Melton - 3-0.13▲5 · 1-0 ball called strike
Miguel Vargas vs Troy Melton
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
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 strike, robot ruled ball: 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 2 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
