“An honest evening's grade: nothing loud, nothing missed by much.”
What this shows — how Laz Diaz called the 146 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 138 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▼2 · 1-2 strike called ball
Brandon Marsh vs Kyle Leahy - 2+0.23▲7 · 0-2 strike called ball
JJ Wetherholt vs Cristopher Sánchez - 3+0.13▲7 · 1-1 strike called ball
Ramón Urías vs Cristopher Sánchez
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.
- 1J.T. Realmuto — ump said strike, robot ruled ball: overturned.
- 2Ramón Urías — ump said ball, robot ruled strike: overturned.
- 3Jordan Walker — ump said strike, robot ruled strike: upheld.
- 4Bryan De La Cruz — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 2 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
