“Squeezed the edges; the hitters didn't mind at all.”
What this shows — how Nick Mahrley called the 135 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 125 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

ABS — the Automated Ball-Strike System
3 pitches went to the robots · 3 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Jonah Heim — ump said ball, robot ruled strike: overturned.
- 2Nolan Schanuel — ump said strike, robot ruled ball: overturned.
- 3Jack Perkins — ump said ball, robot ruled strike: overturned.
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.
