“Generous with the corners — the pitchers said thank you.”
What this shows — how Nick Mahrley called the 145 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 132 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

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
3 pitches went to the robots · 1 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Randy Arozarena — ump said ball, robot ruled strike: overturned.
- 2Colt Emerson — ump said strike, robot ruled strike: upheld.
- 3Justin Foscue — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 3 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
