PHI @ SEA
Home plate: Brian Walsh
“The kind of night where the umpire is the least of the story.”
What this shows — how Brian Walsh called the 139 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 128 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.
