What this shows — how Jansen Visconti called the 158 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 154 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

3 pitches went to the robots · 0 overturned (ump overruled) · 3 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Agustín Ramírez — ump said strike, robot ruled strike: upheld.
  2. 2Agustín Ramírez — ump said strike, robot ruled strike: upheld.
  3. 3Luis Rengifo — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 3 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
