WSH @ ATL
Home plate: Brian Walsh
“If it was close, it was a strike. The hitters noticed.”
What this shows — how Brian Walsh called the 139 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 128 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▲3 · 3-1 ball called strike
CJ Abrams vs JR Ritchie - 2-0.30▼3 · 3-1 ball called strike
Drake Baldwin vs Cade Cavalli - 3+0.30▲9 · 3-1 strike called ball
Jorbit Vivas vs Raisel Iglesias
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 · 3 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1José Tena — ump said strike, robot ruled strike: upheld.
- 2James Wood — ump said strike, robot ruled ball: overturned.
- 3Michael Harris II — ump said strike, robot ruled ball: overturned.
- 4Brady House — ump said strike, robot ruled ball: overturned.
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.
