What this shows — how Alex MacKay called the 147 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 143 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: Daulton Varsho — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).1Challenge 2: Jhostynxon Garcia — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).2Challenge 3: Brandon Valenzuela — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).3Challenge 4: Brandon Valenzuela — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).4

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

4 pitches went to the robots · 1 overturned (ump overruled) · 3 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Daulton Varsho — ump said strike, robot ruled strike: upheld.
  2. 2Jhostynxon Garcia — ump said strike, robot ruled strike: upheld.
  3. 3Brandon Valenzuela — ump said strike, robot ruled ball: overturned.
  4. 4Brandon Valenzuela — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 3 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
