PHI @ SEA
Home plate: Chad Whitson
“Solid and unspectacular — exactly what the job asks.”
What this shows — how Chad Whitson called the 172 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 161 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+0.39▼3 · 2-2 strike called ball
Taylor Ward vs Zack Wheeler - 2+0.20▲1 · 2-1 strike called ball
Kyle Schwarber vs Logan Gilbert - 3+0.13▲1 · 1-1 strike called ball
Bryce Harper vs Logan Gilbert
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.
- 1Cal Raleigh — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 0 of 1 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
