HOU @ SF
Home plate: Mark Wegner
“Expanded the plate a touch past its 17 inches.”
What this shows — how Mark Wegner called the 155 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 141 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

Yordan Alvarez vs Blade Tidwell - 2-0.30▼1 · 3-1 ball called strike
Willy Adames vs Hayden Wesneski - 3-0.28▼4 · 1-2 ball called strike
Willy Adames vs Hayden Wesneski
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
4 pitches went to the robots · 2 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Jose Altuve — ump said ball, robot ruled strike: overturned.
- 2Christian Vázquez — ump said ball, robot ruled ball: upheld.
- 3Drew Cavanaugh — ump said ball, robot ruled ball: upheld.
- 4Yainer Diaz — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 2 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
