Home plate: Nick Mahrley
“Solid and unspectacular — exactly what the job asks.”
What this shows — how Nick Mahrley called the 174 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 160 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.
The zone, as he called it
The calls that moved the game
- 1+0.28▲3 · 1-2 strike called ball
Jazz Chisholm Jr. vs Bailey Falter - 2+0.21▲3 · 3-0 strike called ball· challenged ✓
Aaron Judge vs Luinder Avila - 3+0.20▼2 · 2-1 strike called ball
Nick Loftin vs Cam Schlittler
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
2 pitches went to the robots · 1 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Jazz Chisholm Jr. — ump said strike, robot ruled strike: upheld.
- 2Salvador Perez — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 2 of 2 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
