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, or, on a pitch the ABS (Automated Ball-Strike System) reviewed on a challenge, against its ruling. 95 were right. Below, only the misses are plotted, alongside every challenged pitch.
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). Where the two disagree, the umpire is graded on the ABS ruling.
