Home plate: Vic Carapazza
“A steady night's work behind the plate.”
What this shows — how Vic Carapazza called the 189 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 179 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+0.30▼5 · 3-1 strike called ball
Nolan Arenado vs Gage Jump - 2+0.30▼6 · 3-1 strike called ball
Nolan Arenado vs Yunior Tur - 3-0.21▼1 · 3-0 ball called strike
Geraldo Perdomo vs Gage Jump
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 · 2 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Gabriel Moreno — ump said strike, robot ruled strike: upheld.
- 2Jonah Heim — ump said strike, robot ruled ball: overturned.
- 3James McCann — ump said ball, robot ruled strike: overturned.
- 4Jonah Heim — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 2 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
