Home plate: Adam Hamari
“The zone kept to itself — the hitters said thanks.”
What this shows — how Adam Hamari called the 135 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 122 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

5 pitches went to the robots · 4 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1William Contreras — ump said ball, robot ruled ball: upheld.
- 2William Contreras — ump said ball, robot ruled strike: overturned.
- 3William Contreras — ump said ball, robot ruled strike: overturned.
- 4Jonah Heim — ump said ball, robot ruled strike: overturned.
- 5Christian Yelich — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 3 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
