CHC @ PIT
Home plate: Jansen Visconti
“The zone showed up, did the job, and went home. Ideal.”
What this shows — how Jansen Visconti called the 148 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 143 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
3 pitches went to the robots · 0 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Braxton Ashcraft — ump said ball, robot ruled ball: upheld.
- 2Carson Kelly — ump said ball, robot ruled ball: upheld.
- 3Shawn Ross — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 2 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
