Home plate: Ryan Wills
“One of those nights the challenge system was invented for.”
What this shows — how Ryan Wills called the 126 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 115 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+0.39▲9 · 2-2 strike called ball
Lane Thomas vs Justin Bruihl - 2-0.19▼8 · 2-0 ball called strike
José Fermín vs Daniel Lynch IV - 3-0.13▼3 · 1-1 ball called strike
JJ Wetherholt vs Stephen Kolek
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 · 2 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Maikel Garcia — ump said strike, robot ruled ball: overturned.
- 2Salvador Perez — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 1 of 2 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
