CLE @ COL
Home plate: Nate Tomlinson
“The kind of night where the umpire is the least of the story.”
What this shows — how Nate Tomlinson called the 158 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 150 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

Mickey Moniak vs Joey Cantillo - 2-0.20▼7 · 2-1 ball called strike
Kyle Karros vs Colin Holderman - 3+0.10▼3 · 0-1 strike called ball
Jake McCarthy vs Joey Cantillo
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 · 1 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Patrick Bailey — ump said ball, robot ruled ball: upheld.
- 2Willi Castro — ump said strike, robot ruled strike: upheld.
- 3Patrick Bailey — ump said strike, robot ruled ball: 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.
