SF @ PHI
Home plate: David Rackley
“Down the middle. Both dugouts had the same zone.”
What this shows — how David Rackley called the 185 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 173 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+0.69▼3 · 3-2 strike called ball
Kyle Schwarber vs Adrian Houser - 2-0.30▼5 · 3-1 ball called strike
Adolis García vs Ryan Borucki - 3+0.23▲3 · 0-2 strike called ball
Rafael Devers vs Nolan Hoffman
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 · 2 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Garrett Stubbs — ump said ball, robot ruled ball: upheld.
- 2Jung Hoo Lee — ump said strike, robot ruled strike: upheld.
- 3Jung Hoo Lee — ump said strike, robot ruled ball: overturned.
- 4Eric Haase — ump said ball, robot ruled ball: upheld.
- 5Bryce Harper — 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), not our error.
