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, or, on a pitch the ABS (Automated Ball-Strike System) reviewed on a challenge, against its ruling. 145 were right. Below, only the misses are plotted, alongside every challenged pitch.
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). Where the two disagree, the umpire is graded on the ABS ruling.
