Home plate: Brian Walsh
“A workmanlike night — nothing to frame, nothing to fix.”
What this shows — how Brian Walsh called the 150 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 141 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▼7 · 3-1 ball called strike· challenged
Tommy Edman vs Michael Wacha - 2-0.28▲8 · 1-2 ball called strike
Kyle Isbel vs Evan Phillips - 3+0.19▲5 · 2-0 strike called ball
John Rave vs Blake Snell
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
7 pitches went to the robots · 4 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Nick Loftin — ump said ball, robot ruled strike: overturned.
- 2Ben Rortvedt — ump said strike, robot ruled ball: overturned.
- 3Carter Jensen — ump said strike, robot ruled strike: upheld.
- 4Ben Rortvedt — ump said ball, robot ruled ball: upheld.
- 5Tommy Edman — ump said strike, robot ruled strike: upheld.
- 6Michael Massey — ump said ball, robot ruled strike: overturned.
- 7Hunter Feduccia — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 2 of 7 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
