LAA @ BOS
Home plate: Mark Wegner
“Off the corner was close enough tonight.”
What this shows — how Mark Wegner called the 171 pitches that were taken (no swing), graded against the tracked rulebook strike zone, or, on a pitch the ABS (Automated Ball-Strike System) reviewed on a challenge, against its ruling. 159 were right. Below, only the misses are plotted, alongside every challenged pitch.

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 · 1 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Caleb Durbin — ump said strike, robot ruled ball: overturned.
- 2Jarren Duran — ump said strike, robot ruled strike: upheld.
- 3Tyler Heineman — ump said ball, robot ruled ball: upheld.
- 4Zach Neto — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 4 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone). Where the two disagree, the umpire is graded on the ABS ruling.
