What this shows — how Tripp Gibson called the 130 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 125 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: Josh Naylor — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).1Challenge 2: Josh Naylor — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).2Challenge 3: Vinnie Pasquantino — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).3Challenge 4: Carter Jensen — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).4Challenge 5: Maikel Garcia — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).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 · 3 overturned (ump overruled) · 2 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Josh Naylor — ump said strike, robot ruled strike: upheld.
  2. 2Josh Naylor — ump said ball, robot ruled strike: overturned.
  3. 3Vinnie Pasquantino — ump said strike, robot ruled strike: upheld.
  4. 4Carter Jensen — ump said strike, robot ruled ball: overturned.
  5. 5Maikel Garcia — ump said ball, robot ruled strike: overturned.

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.
