WSH @ ATL
Home plate: John Bacon
“The kind of night where the umpire is the least of the story.”
What this shows — how John Bacon called the 130 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 123 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+0.13▼7 · 1-0 strike called ball
Dominic Smith vs Riley Cornelio - 2+0.13▲8 · 1-0 strike called ball
Luis García Jr. vs Danny Young - 3+0.09▲1 · 0-0 strike called ball
James Wood vs Martín Pérez
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
6 pitches went to the robots · 3 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Keibert Ruiz — ump said ball, robot ruled strike: overturned.
- 2Dominic Smith — ump said strike, robot ruled ball: overturned.
- 3Keibert Ruiz — ump said ball, robot ruled ball: upheld.
- 4Dominic Smith — ump said strike, robot ruled strike: upheld.
- 5Dylan Crews — ump said strike, robot ruled strike: upheld.
- 6Matt Olson — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 4 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
