“Borderline went to the battery all night.”
What this shows — how Jansen Visconti called the 150 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 136 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

Donovan Walton vs Lucas Erceg - 3-0.21▼2 · 3-0 ball called strike
Kyle Isbel vs Mason Barnett
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.
- 1Donovan Walton — ump said ball, robot ruled strike: overturned.
- 2Brian Serven — ump said ball, robot ruled ball: upheld.
- 3Carter Jensen — ump said ball, robot ruled ball: upheld.
- 4Carter Jensen — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 2 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
