“A workmanlike night — nothing to frame, nothing to fix.”
What this shows — how Nick Mahrley called the 154 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 143 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
4 pitches went to the robots · 2 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1William Contreras — ump said ball, robot ruled ball: upheld.
- 2Manny Machado — ump said strike, robot ruled ball: overturned.
- 3Xander Bogaerts — ump said strike, robot ruled ball: overturned.
- 4William Contreras — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 3 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
