PHI @ MIL
Home plate: Erich Bacchus
“The kind of night where the umpire is the least of the story.”
What this shows — how Erich Bacchus called the 130 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 123 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

Run impact from the count run-value table: a missed strike three is worth far more than one on 3-0.

- 1Edmundo Sosa — ump said strike, robot ruled ball: overturned.
- 2Gary Sánchez — ump said ball, robot ruled strike: overturned.
- 3Gary Sánchez — ump said ball, robot ruled strike: overturned.
- 4Rafael Marchán — ump said ball, robot ruled strike: overturned.
- 5Bryce Harper — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 5 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
