ATL @ PHI
Home plate: Todd Tichenor
“An honest evening's grade: nothing loud, nothing missed by much.”
What this shows — how Todd Tichenor called the 140 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. 131 were right. Below, only the misses are plotted, alongside every challenged pitch.
The zone, as he called it
* 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
5 pitches went to the robots · 1 overturned (ump overruled) · 4 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1J.T. Realmuto — ump said ball, robot ruled strike: overturned.
- 2Alec Bohm — ump said strike, robot ruled strike: upheld.
- 3Drake Baldwin — ump said ball, robot ruled ball: upheld.
- 4Ha-Seong Kim — ump said strike, robot ruled strike: upheld.
- 5J.T. Realmuto — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 4 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone). Where the two disagree, the umpire is graded on the ABS ruling.
