WSH @ ATL
Home plate: Brian Walsh
“Nothing that'll trend, and on this beat that's a compliment.”
What this shows — how Brian Walsh called the 139 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 131 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 ball, robot ruled strike: overturned.
- 3Michael Harris II — ump said ball, robot ruled strike: overturned.
- 4Brady House — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 1 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
