“Somebody's pitching staff sent a thank-you note.”
What this shows — how Nick Mahrley called the 158 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
5 pitches went to the robots · 2 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Shohei Ohtani — ump said strike, robot ruled strike: upheld.
- 2Andrew Knizner — ump said ball, robot ruled ball: upheld.
- 3Andrew Knizner — ump said ball, robot ruled strike: overturned.
- 4Andrew Knizner — ump said ball, robot ruled strike: overturned.
- 5Osleivis Basabe — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 4 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
