Home plate: Chris Guccione
“The kind of night where the umpire is the least of the story.”
What this shows — how Chris Guccione called the 171 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 162 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.
