HOU @ CIN
Home plate: David Rackley
“An honest evening's grade: nothing loud, nothing missed by much.”
What this shows — how David Rackley called the 130 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 124 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
4 pitches went to the robots · 2 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Cam Smith — ump said strike, robot ruled strike: upheld.
- 2Sal Stewart — ump said strike, robot ruled ball: overturned.
- 3Jose Altuve — ump said strike, robot ruled ball: overturned.
- 4Jose Trevino — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 4 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
