Home plate: John Tumpane
“The kind of night where the umpire is the least of the story.”
What this shows — how John Tumpane called the 166 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 158 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 · 2 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Andrew Knizner — ump said ball, robot ruled strike: overturned.
- 2Brett Harris — ump said strike, robot ruled strike: upheld.
- 3Josue De Paula — ump said strike, robot ruled strike: upheld.
- 4Tommy Edman — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 4 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
