Home plate: John Bacon
“Nothing that'll trend, and on this beat that's a compliment.”
What this shows — how John Bacon called the 128 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 120 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
Bryce Eldridge vs Michael Lorenzen - 2+0.39▲9 · 2-2 strike called ball
Willi Castro vs Dylan Smith - 3-0.20▼6 · 2-1 ball called strike
Drew Gilbert vs Tanner Gordon
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.
- 1Drew Cavanaugh — ump said ball, robot ruled ball: upheld.
- 2Logan Webb — ump said strike, robot ruled ball: overturned.
- 3Brett Sullivan — ump said strike, robot ruled ball: overturned.
- 4Brett Sullivan — ump said ball, robot ruled ball: upheld.
- 5Brett Sullivan — ump said strike, robot ruled ball: overturned.
- 6Turner Hill — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 3 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
