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. He got 130 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

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), not our error.
