BOS @ PIT
Home plate: Ryan Additon
“The kind of night where the umpire is the least of the story.”
What this shows — how Ryan Additon called the 144 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+0.39▲4 · 2-2 strike called ball

Adley Rutschman vs Wilber Dotel - 3-0.13▼1 · 1-1 ball called strike
Esmerlyn Valdez vs Sonny Gray
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.
- 1Rafael Flores Jr. — ump said strike, robot ruled ball: overturned.
- 2Rafael Flores Jr. — ump said ball, robot ruled ball: upheld.
- 3Adley Rutschman — ump said ball, robot ruled ball: upheld.
- 4Adley Rutschman — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 2 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
