Home plate: Dexter Kelley
“The kind of night where the umpire is the least of the story.”
What this shows — how Dexter Kelley called the 200 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 186 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▲8 · 3-2 ball called strike
Brendan Donovan vs Bryse Wilson - 2-0.21▼8 · 3-0 ball called strike
Andrew Vaughn vs Seranthony Domínguez - 3+0.19▲7 · 2-0 strike called ball
Cole Young vs Bryse Wilson
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 · 1 overturned (ump overruled) · 4 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1William Contreras — ump said ball, robot ruled ball: upheld.
- 2William Contreras — ump said ball, robot ruled ball: upheld.
- 3Randy Arozarena — ump said strike, robot ruled strike: upheld.
- 4Brendan Donovan — ump said ball, robot ruled strike: overturned.
- 5Taylor Ward — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 5 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
