“The zone leaned, and the ledger noticed.”
What this shows — how Clint Vondrak called the 171 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 159 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

Michael Busch vs Jakob Junis - 3+0.23▲6 · 0-2 strike called ball

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.
- 1Jake Burger — ump said strike, robot ruled ball: overturned.
- 2Corey Seager — ump said strike, robot ruled strike: upheld.
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.
