Home plate: Jansen Visconti
“The kind of night where the umpire is the least of the story.”
What this shows — how Jansen Visconti called the 135 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 127 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+0.28▼6 · 1-2 strike called ball
Jim Jarvis vs Nolan McLean - 2+0.13▼7 · 1-1 strike called ball· challenged
Lane Thomas vs Jefry Yan - 3+0.13▲1 · 1-0 strike called ball
A.J. Ewing vs Martín Pérez
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 · 0 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Francisco Alvarez — ump said ball, robot ruled ball: upheld.
- 2Francisco Alvarez — ump said ball, robot ruled ball: upheld.
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.
