HOU @ TOR
Home plate: Brian Walsh
“Tonight's zone had a rooting interest.”
What this shows — how Brian Walsh called the 199 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 182 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+0.28▼9 · 1-2 strike called ball
Nathan Lukes vs Josh Hader - 2+0.20▼5 · 2-1 strike called ball
Brandon Valenzuela vs Peter Lambert - 3+0.19▼5 · 2-0 strike called ball
Kazuma Okamoto vs Peter Lambert
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 · 2 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Yainer Diaz — ump said ball, robot ruled ball: upheld.
- 2Taylor Trammell — ump said strike, robot ruled ball: overturned.
- 3Brice Matthews — ump said strike, robot ruled strike: upheld.
- 4Jesús Sánchez — ump said strike, robot ruled strike: upheld.
- 5Brandon Valenzuela — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 5 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
