What this shows — how Ben May called the 176 pitches that were taken (no swing), graded against the tracked rulebook strike zone, or, on a pitch the ABS (Automated Ball-Strike System) reviewed on a challenge, against its ruling. 165 were right. Below, only the misses are plotted, alongside every challenged pitch.

The zone, as he called it

Challenge 1: Carson Kelly — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled). Our tracking puts it on the other side of the line; the grade follows the ruling.1*Challenge 2: Alex Bregman — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).2Challenge 3: Owen Caissie — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).3Challenge 4: Carson Kelly — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).4Challenge 5: Brian Navarreto — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).5Challenge 6: Pedro Ramírez — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).6

* Graded on the ABS ruling. ABS measures its own zone, set by the batter’s height and taken at the middle of the plate, and our tracking puts this pitch on the other side of the line.

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 the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Carson Kelly — ump said ball, robot ruled strike: overturned.
  2. 2Alex Bregman — ump said strike, robot ruled ball: overturned.
  3. 3Owen Caissie — ump said strike, robot ruled strike: upheld.
  4. 4Carson Kelly — ump said ball, robot ruled strike: overturned.
  5. 5Brian Navarreto — ump said ball, robot ruled ball: upheld.
  6. 6Pedro Ramírez — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 5 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone). Where the two disagree, the umpire is graded on the ABS ruling.
