Home plate: Tripp Gibson
“An honest evening's grade: nothing loud, nothing missed by much.”
What this shows — how Tripp Gibson called the 149 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 139 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

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
3 pitches went to the robots · 3 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Eric Haase — ump said ball, robot ruled strike: overturned.
- 2Nolan Arenado — ump said strike, robot ruled ball: overturned.
- 3Geraldo Perdomo — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 3 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
