Home plate: John Tumpane
“Called it the way the rulebook drew it up.”
What this shows — how John Tumpane called the 157 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 150 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

Ronald Acuña Jr. vs DL Hall - 2+0.13▼8 · 1-1 strike called ball
Luis Lara vs Brent Suter - 3-0.13▼2 · 1-0 ball called strike
Joey Ortiz vs Martín Pérez
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
2 pitches went to the robots · 1 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1William Contreras — ump said strike, robot ruled ball: overturned.
- 2William Contreras — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 0 of 2 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
