Home plate: Junior Valentine
“The zone showed up, did the job, and went home. Ideal.”
What this shows — how Junior Valentine called the 157 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 152 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

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.
- 1Sandy León — ump said ball, robot ruled strike: overturned.
- 2Eric Haase — ump said ball, robot ruled strike: 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.
