BAL @ STL
Home plate: Jansen Visconti
“The zone kept its promises.”
What this shows — how Jansen Visconti called the 171 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 165 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+0.39▼1 · 2-2 strike called ball
Iván Herrera vs Kyle Bradish - 2+0.13▼7 · 1-1 strike called ball
Jordan Walker vs Rico Garcia - 3-0.13▼6 · 1-0 ball called strike
JJ Wetherholt vs Josh Walker
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.
- 1Dylan Beavers — ump said strike, robot ruled strike: upheld.
- 2Josh Walker — ump said ball, robot ruled ball: upheld.
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.
