CIN @ STL
Home plate: Chris Conroy
“Solid and unspectacular — exactly what the job asks.”
What this shows — how Chris Conroy called the 208 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 196 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
Iván Herrera vs Brady Singer - 2+0.30▼6 · 3-1 strike called ball
Jimmy Crooks vs Luis Mey - 3+0.21▲8 · 3-0 strike called ball
Sal Stewart vs Hunter Dobbins
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.
- 1Tyler Stephenson — ump said ball, robot ruled ball: upheld.
- 2Tyler Stephenson — ump said ball, robot ruled strike: overturned.
- 3Iván Herrera — ump said strike, robot ruled strike: upheld.
- 4Sal Stewart — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 2 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
