MIA @ PIT
Home plate: Junior Valentine
“The kind of night where the umpire is the least of the story.”
What this shows — how Junior Valentine called the 144 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 136 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
3 pitches went to the robots · 1 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Ryan O'Hearn — ump said strike, robot ruled strike: upheld.
- 2Otto Lopez — ump said strike, robot ruled ball: overturned.
- 3Joe Mack — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 3 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
