AZ @ BOS
Home plate: Dan Iassogna
“Generous with the corners — the pitchers said thank you.”
What this shows — how Dan Iassogna called the 148 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 137 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▲2 · 1-2 ball called strike
Geraldo Perdomo vs Alec Gamboa - 2-0.23▲7 · 0-2 ball called strike
Jose Fernandez vs Greg Weissert - 3-0.21▼3 · 3-0 ball called strike
Adley Rutschman vs Mitch Bratt
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 · 4 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Gabriel Moreno — ump said strike, robot ruled ball: overturned.
- 2Geraldo Perdomo — ump said ball, robot ruled strike: overturned.
- 3Nick Sogard — ump said ball, robot ruled strike: overturned.
- 4Adley Rutschman — ump said strike, robot ruled ball: overturned.
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.
