What this shows — how Sean Barber called the 156 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 146 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

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 · 0 overturned (ump overruled) · 4 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Jordan Walker — ump said strike, robot ruled strike: upheld.
  2. 2Salvador Perez — ump said ball, robot ruled ball: upheld.
  3. 3Jimmy Crooks — ump said strike, robot ruled strike: upheld.
  4. 4Nick Loftin — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 4 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
