MIA @ ATL
Home plate: Clint Vondrak
“The kind of night where the umpire is the least of the story.”
What this shows — how Clint Vondrak called the 115 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 109 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+0.69▲5 · 3-2 strike called ball
Owen Caissie vs Bryce Elder - 2-0.13▼7 · 1-1 ball called strike
Ozzie Albies vs Cade Gibson - 3+0.10▼1 · 0-1 strike called ball
Matt Olson vs Eury 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.
- 1Joe Mack — ump said strike, robot ruled ball: overturned.
- 2Ronald Acuña Jr. — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 1 of 2 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
