Home plate: Chris Conroy
“A steady night's work behind the plate.”
What this shows — how Chris Conroy called the 170 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 161 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
- 1-0.21▲9 · 3-0 ball called strike
James McCann vs Nick Raquet - 2+0.19▼3 · 2-0 strike called ball
Leody Taveras vs Merrill Kelly - 3+0.19▼7 · 2-0 strike called ball
Gunnar Henderson vs Taylor Clarke
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 · 1 overturned (ump overruled) · 4 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Samuel Basallo — ump said ball, robot ruled ball: upheld.
- 2James McCann — ump said ball, robot ruled ball: upheld.
- 3James McCann — ump said ball, robot ruled ball: upheld.
- 4Pete Alonso — ump said strike, robot ruled ball: overturned.
- 5Dylan Beavers — ump said strike, robot ruled strike: upheld.
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.
