AZ @ PIT
Home plate: Chris Conroy
“Reliable as a Tuesday: no complaints, no headlines.”
What this shows — how Chris Conroy called the 112 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 104 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.
The zone, as he called it
The calls that moved the game
- 1+0.30▲5 · 3-1 strike called ball
Ildemaro Vargas vs Jared Jones - 2-0.28▲2 · 1-2 ball called strike
Max Kepler vs Jared Jones - 3+0.13▼4 · 1-1 strike called ball
Esmerlyn Valdez vs Eduardo Rodriguez
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
1 pitch went to the robots · 0 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Henry Davis — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 0 of 1 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
