At 8:46 a.m. local time, less than two hours after golf resumed followed a 91-day hiatus, a horn blew at Colonial Country Club to halt play.
The PGA Tour reserved that time for a moment of silence, in memory of the late George Floyd and as a reminder of social and racial injustice in the U.S.
Eight minutes, 46 seconds is the length of time prosecutors say Floyd, a 46-year-old black man, was pinned to the ground under a Minneapolis police officer's knee before he died on May 25.
Players on the course and everyone throughout the Colonial grounds paused for a minute, before the horn was sounded again for play to resume.
