KC @ BOS
Home plate: Alan Porter
“You had to throw it down Broadway to get the call.”
What this shows — how Alan Porter called the 156 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 145 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+0.30▼3 · 3-1 strike called ball
Adley Rutschman vs Seth Lugo - 2+0.30▲6 · 3-1 strike called ball
John Rave vs Sonny Gray - 3-0.19▲1 · 2-0 ball called strike
Bobby Witt Jr. 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
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.
- 1Carter Jensen — ump said ball, robot ruled strike: overturned.
- 2Caleb Durbin — ump said strike, robot ruled strike: upheld.
- 3Adley Rutschman — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 3 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
