“Called a fair game and let the players decide it.”
What this shows — how Tyler Jones called the 174 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 166 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

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.
- 1Carson Kelly — ump said ball, robot ruled strike: overturned.
- 2Pete Crow-Armstrong — ump said strike, robot ruled ball: overturned.
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.
