What this shows — how Mark Wegner called the 137 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 124 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 · 1 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Gunnar Henderson — ump said strike, robot ruled ball: overturned.
- 2Pete Alonso — ump said strike, robot ruled strike: upheld.
- 3Brandon Valenzuela — 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.
