TB @ ATL
Home plate: Jansen Visconti
“Squeezed the edges; the hitters didn't mind at all.”
What this shows — how Jansen Visconti called the 103 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 95 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+0.20▼7 · 2-1 strike called ball
Michael Harris II vs Cam Booser - 2+0.13▲2 · 1-1 strike called ball
Nick Fortes vs Martín Pérez - 3-0.13▼7 · 1-1 ball called strike
Ronald Acuña Jr. vs Nick Martinez
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 · 2 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Martín Pérez — ump said ball, robot ruled ball: upheld.
- 2Nick Fortes — ump said ball, robot ruled strike: overturned.
- 3Nick Fortes — ump said ball, robot ruled strike: overturned.
- 4Liam Hicks — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 4 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
