CHC @ MIA
Home plate: Chris Conroy
“The corners were friendlier in one direction tonight.”
What this shows — how Chris Conroy called the 195 pitches that were taken (no swing), graded against the tracked rulebook strike zone, or, on a pitch the ABS (Automated Ball-Strike System) reviewed on a challenge, against its ruling. 185 were right. Below, only the misses are plotted, alongside every challenged pitch.
The zone, as he called it
* Graded on the ABS ruling. ABS measures its own zone, set by the batter’s height and taken at the middle of the plate, and our tracking puts this pitch on the other side of the line.
The calls that moved the game
- 1+0.69▲7 · 3-2 strike called ball

Griffin Conine vs Ryan Zeferjahn - 3-0.39▼3 · 2-2 ball called strike
Heriberto Hernández vs Javier Assad
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
5 pitches went to the robots · 3 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Miguel Amaya — ump said ball, robot ruled ball: upheld.
- 2Joe Mack — ump said ball, robot ruled strike: overturned.
- 3Joe Mack — ump said ball, robot ruled strike: overturned.
- 4Heriberto Hernández — ump said strike, robot ruled strike: upheld.
- 5Griffin Conine — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 4 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone). Where the two disagree, the umpire is graded on the ABS ruling.
