What this shows — how Steven Jaschinski called the 156 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 148 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

ABS — the Automated Ball-Strike System

5 pitches went to the robots · 3 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Spencer Jones — ump said strike, robot ruled strike: upheld.
  2. 2Christian Vázquez — ump said ball, robot ruled ball: upheld.
  3. 3Jose Altuve — ump said ball, robot ruled strike: overturned.
  4. 4José Caballero — ump said ball, robot ruled strike: overturned.
  5. 5Austin Wells — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 2 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
