Home plate: Tyler Jones
“The kind of night where the umpire is the least of the story.”
What this shows — how Tyler Jones called the 179 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 168 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+0.69▼3 · 3-2 strike called ball
Bryce Eldridge vs Ben Brown - 2+0.28▼4 · 1-2 strike called ball
Drew Gilbert vs Ben Brown - 3+0.28▼7 · 1-2 strike called ball
Casey Schmitt vs Caleb Thielbar
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 · 1 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Nico Hoerner — ump said strike, robot ruled strike: upheld.
- 2Eric Haase — ump said ball, robot ruled ball: upheld.
- 3Michael Busch — ump said strike, robot ruled strike: upheld.
- 4Drew Gilbert — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 3 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
