PIT @ AZ
Home plate: Brennan Miller
“The kind of night where the umpire is the least of the story.”
What this shows — how Brennan Miller called the 152 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 143 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▲7 · 0-2 strike called ball
Ryan O'Hearn vs Brandyn Garcia - 2+0.13▼1 · 1-0 strike called ball
Geraldo Perdomo vs Mitch Keller - 3-0.13▲9 · 1-0 ball called strike
Brandon Lowe vs Paul Sewald
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 · 1 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Joey Bart — ump said ball, robot ruled ball: upheld.
- 2James McCann — ump said ball, robot ruled strike: overturned.
- 3Dennis Santana — ump said ball, robot ruled ball: upheld.
- 4Jorge Barrosa — ump said strike, robot ruled strike: upheld.
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.
