HOU @ SF
Home plate: Steven Jaschinski
“Solid and unspectacular — exactly what the job asks.”
What this shows — how Steven Jaschinski called the 147 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 139 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

Jose Altuve vs Carson Whisenhunt - 3-0.21▲1 · 3-0 ball called strike
Nelson Velázquez vs Carson Whisenhunt
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.
- 1Drew Cavanaugh — ump said strike, robot ruled ball: overturned.
- 2Yainer Diaz — ump said ball, robot ruled ball: upheld.
- 3Jung Hoo Lee — ump said strike, robot ruled strike: upheld.
- 4Nelson Velázquez — ump said strike, robot ruled strike: upheld.
- 5Drew Cavanaugh — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 4 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
