What this shows — how John Libka called the 140 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 134 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

Challenge 1: Drew Romo — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).1Challenge 2: Freddy Fermin — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).2Challenge 3: Freddy Fermin — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).3Challenge 4: Miguel Andujar — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).4Challenge 5: Chase Meidroth — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).5

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 · 2 overturned (ump overruled) · 3 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Drew Romo — ump said ball, robot ruled ball: upheld.
  2. 2Freddy Fermin — ump said strike, robot ruled ball: overturned.
  3. 3Freddy Fermin — ump said strike, robot ruled ball: overturned.
  4. 4Miguel Andujar — ump said strike, robot ruled strike: upheld.
  5. 5Chase Meidroth — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 3 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
