What this shows — how Alan Porter called the 120 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 114 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: Mauricio Dubón — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).1Challenge 2: Sandy León — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).2Challenge 3: Carson Benge — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).3Challenge 4: Francisco Alvarez — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).4Challenge 5: Marcus Semien — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).5Challenge 6: Sandy León — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).6

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

  1. 1Mauricio Dubón — ump said ball, robot ruled strike: overturned.
  2. 2Sandy León — ump said ball, robot ruled ball: upheld.
  3. 3Carson Benge — ump said ball, robot ruled strike: overturned.
  4. 4Francisco Alvarez — ump said strike, robot ruled strike: upheld.
  5. 5Marcus Semien — ump said strike, robot ruled strike: upheld.
  6. 6Sandy León — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 3 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
