Home plate: Clint Vondrak
“Down the middle. Both dugouts had the same zone.”
What this shows — how Clint Vondrak called the 165 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 157 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+0.23▼4 · 0-2 strike called ball
José Fermín vs David Peterson - 2-0.20▲8 · 2-1 ball called strike
Pete Crow-Armstrong vs Hunter Dobbins - 3-0.19▲7 · 2-0 ball called strike
Michael Busch vs Hunter Dobbins
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
5 pitches went to the robots · 3 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Miguel Amaya — ump said strike, robot ruled ball: overturned.
- 2Jordan Walker — ump said strike, robot ruled strike: upheld.
- 3Miguel Amaya — ump said strike, robot ruled ball: overturned.
- 4Miguel Amaya — ump said strike, robot ruled ball: overturned.
- 5Carson Kelly — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 2 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
