“One of those nights the challenge system was invented for.”
What this shows — how Adam Beck called the 174 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
- 1+0.21▼6 · 3-0 strike called ball
Nick Gonzales vs Julian Garcia - 2+0.19▼6 · 2-0 strike called ball
Nick Gonzales vs Julian Garcia - 3+0.13▼2 · 1-1 strike called ball
Nick Gonzales vs Brady Singer
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 · 1 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Brandon Lowe — ump said strike, robot ruled ball: overturned.
- 2Tyler Stephenson — ump said ball, robot ruled ball: upheld.
- 3Henry Davis — ump said ball, robot ruled ball: upheld.
- 4Jake Mangum — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 4 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
