What this shows — how Jansen Visconti called the 158 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 147 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: Mark Vientos — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).1Challenge 2: Liam Hicks — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).2Challenge 3: Liam Hicks — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).3Challenge 4: Otto Lopez — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).4Challenge 5: Luis Torrens — the ump called it a strike, the robot ruled ball (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 · 4 overturned (ump overruled) · 1 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Mark Vientos — ump said ball, robot ruled strike: overturned.
  2. 2Liam Hicks — ump said strike, robot ruled ball: overturned.
  3. 3Liam Hicks — ump said ball, robot ruled ball: upheld.
  4. 4Otto Lopez — ump said ball, robot ruled strike: overturned.
  5. 5Luis Torrens — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 1 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
