“Squeezed the edges; the hitters didn't mind at all.”
What this shows — how Mark Wegner called the 147 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 136 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.
- 1Jhonny Pereda — ump said ball, robot ruled ball: upheld.
- 2Jonah Heim — ump said ball, robot ruled strike: overturned.
- 3Jhonny Pereda — ump said ball, robot ruled ball: 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.
