HOU @ PHI
Home plate: Dan Iassogna
“The zone kept its promises.”
What this shows — how Dan Iassogna called the 153 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. 146 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+0.23▲1 · 0-2 strike called ball
Jose Altuve vs Andrew Painter - 2+0.20▲8 · 2-1 strike called ball
Yordan Alvarez vs Chase Shugart - 3-0.19▲9 · 2-0 ball called strike
Isaac Paredes vs José Alvarado
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
5 pitches went to the robots · 1 overturned (ump overruled) · 4 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Taylor Trammell — ump said strike, robot ruled strike: upheld.
- 2J.T. Realmuto — ump said ball, robot ruled strike: overturned.
- 3Cam Smith — ump said strike, robot ruled strike: upheld.
- 4Kyle Schwarber — ump said strike, robot ruled strike: upheld.
- 5Alec Bohm — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 5 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone). Where the two disagree, the umpire is graded on the ABS ruling.
