AZ @ BOS
Home plate: D.J. Reyburn
“Down the middle. Both dugouts had the same zone.”
What this shows — how D.J. Reyburn called the 156 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 152 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

Mickey Gasper vs Merrill Kelly - 2+0.20▼5 · 2-1 strike called ball
Adley Rutschman vs Merrill Kelly - 3-0.10▲6 · 0-1 ball called strike
Jordan Lawlar vs Tyron Guerrero
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
5 pitches went to the robots · 2 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Willson Contreras — ump said strike, robot ruled strike: upheld.
- 2Geraldo Perdomo — ump said ball, robot ruled strike: overturned.
- 3James McCann — ump said ball, robot ruled ball: upheld.
- 4Geraldo Perdomo — ump said ball, robot ruled strike: overturned.
- 5James McCann — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 3 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
