Home plate: Chad Whitson
“A workmanlike night — nothing to frame, nothing to fix.”
What this shows — how Chad Whitson called the 142 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 135 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+0.20▲7 · 2-1 strike called ball
Matt Chapman vs Ryan Thompson - 2-0.13▲5 · 1-0 ball called strike
Will Brennan vs Zac Gallen - 3-0.13▼5 · 1-0 ball called strike
Corbin Carroll vs JT Brubaker
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
1 pitch went to the robots · 1 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Gabriel Moreno — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 1 of 1 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
