BOS @ COL
Home plate: Chris Conroy
“The zone showed up, did the job, and went home. Ideal.”
What this shows — how Chris Conroy called the 107 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 103 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

Cole Carrigg vs Tyron Guerrero - 3-0.09▲7 · 0-0 ball called strike
Ceddanne Rafaela vs Brennan Bernardino
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 · 2 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Hunter Goodman — ump said ball, robot ruled strike: overturned.
- 2Mickey Gasper — ump said ball, robot ruled ball: upheld.
- 3Hunter Goodman — ump said ball, robot ruled strike: overturned.
- 4Hunter Goodman — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 2 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
