Home plate: Dan Iassogna
“An honest evening's grade: nothing loud, nothing missed by much.”
What this shows — how Dan Iassogna called the 155 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 148 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

John Rave vs Colin Rea - 3+0.13▲8 · 1-0 strike called ball

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.
- 1Nick Loftin — ump said ball, robot ruled strike: overturned.
- 2Michael Busch — ump said ball, robot ruled strike: overturned.
- 3Alex Bregman — ump said strike, robot ruled strike: upheld.
- 4Carter Jensen — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 1 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
