It was after four initial pair holes (par four) at Shriners Hospitals for Children Open that Henrik Norlander struck with his hole-in-one.
The course's fifth hole is 196 yards (just under 180 meters) long.
The hit was the start of a good period for Norlander who put birdies on both the seventh and eighth hole.
But then it stopped by a couple of birdies and a couple of bogeys and he landed in a shared 32nd place with -4 after the first round, five strokes behind the leader Bryson DeChambeau, USA.
