What this shows — how Nic Lentz called the 163 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 157 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

6 pitches went to the robots · 2 overturned (ump overruled) · 4 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Francisco Alvarez — ump said ball, robot ruled ball: upheld.
  2. 2Pedro Pagés — ump said strike, robot ruled ball: overturned.
  3. 3Matthew Liberatore — ump said ball, robot ruled ball: upheld.
  4. 4Freddy Peralta — ump said strike, robot ruled ball: overturned.
  5. 5Francisco Alvarez — ump said ball, robot ruled ball: upheld.
  6. 6Thomas Saggese — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 4 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
