SF @ BOS
Home plate: James Jean
“If it was close, it was a strike. The hitters noticed.”
What this shows — how James Jean called the 106 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 97 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

Caleb Durbin vs Matt Wilkinson - 2-0.30▼2 · 3-1 ball called strike
Nick Sogard vs Matt Wilkinson - 3+0.28▼7 · 1-2 strike called ball
Willson Contreras vs Sam Hentges
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
3 pitches went to the robots · 2 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Andrew Knizner — ump said strike, robot ruled ball: overturned.
- 2Ceddanne Rafaela — ump said strike, robot ruled strike: upheld.
- 3Andrew Knizner — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 1 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
