Home plate: Tyler Jones
“If umpiring had a highlight reel, this wouldn't make it. That's the compliment.”
What this shows — how Tyler Jones called the 174 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+0.13▲7 · 1-1 strike called ball
Pete Crow-Armstrong vs George Soriano - 2+0.10▲6 · 0-1 strike called ball
Ian Happ vs Andre Pallante - 3+0.10▼8 · 0-1 strike called ball
Iván Herrera vs Gavin Hollowell
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
2 pitches went to the robots · 2 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Carson Kelly — ump said strike, robot ruled ball: overturned.
- 2Pete Crow-Armstrong — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 0 of 2 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
