“An honest evening's grade: nothing loud, nothing missed by much.”
What this shows — how Laz Diaz called the 157 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 147 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

Jarren Duran vs Walker Buehler - 2-0.13▲2 · 1-1 ball called strike
Manny Machado vs Ranger Suarez - 3+0.10▲2 · 0-1 strike called ball
Xander Bogaerts vs Ranger Suarez
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
3 pitches went to the robots · 3 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Luis Campusano — ump said ball, robot ruled strike: overturned.
- 2Miguel Andujar — ump said strike, robot ruled ball: overturned.
- 3Luis Campusano — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 2 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
