Suffice to say, if ever there was a time to take advantage of Pebble Beach, this was it.
Tiger Woods had yet to tee off.
Fowler, who is still seeking his first major title, shot a five-under 66 to open his account.
"We are endeavoring to set up and play a U.S. Open as the U.S. Open has always been at Pebble Beach and just let history unfold, as it always has, and it will take care of itself", Bodenhamer said.
Fowler shot a 65 and led after the first round in 2017, finishing in a tie for fifth at Erin Hills.
But only 17 players were under par in the first round of 2000.
It all added up to his lowest opening round in the US Open since the 65 that sent him on his way to his first major success, the Processional at Congressional in 2011, and when one considers that he had been 34-over for his seven first rounds at the US Open since, this was highly welcome.
With Pebble Beach playing soft in cool temperatures, the course was there for the taking by early starters.
Justin Rose was another to make a fast start as he seeks to make amends for two disappointing performances in the majors so far this season.
Not faring as well was Phil Mickelson, who was 1 over through 14 holes.
World number one Koepka tees off at 21:47 BST, with 2019 Masters victor Woods out alongside fellow former champions Jordan Spieth and England's Justin Rose at 22:09. He was 4 under with his birdie on the par-5 sixth hole and appeared to be on another major mission until a few errant tee shots into nasty rough, a few missed putts and a few bogeys.
Shot of the day: Here's that unreal putt on No. 14.
It was an ideal start for Rose and for the USGA, which wants a smooth ride after four years of various mishaps in the U.S. Open.
The 2019 U.S. Open combines with the picturesque views of Pebble Beach in golf's third major on the 2019 calendar. Oosthuzien is at 2 under through seven holes.
Some big names are finding Pebble Beach to their liking in the first round of the U.S. Open.
From there, Woods birdied the par-5 sixth after a short pitch, rolled in a 20-footer for birdie at the par-3 seventh - then made 11 straight pars. That put him at 5 under through six holes in the opening round of the US Open. If he had skipped the Canadian Open, he would've stayed in the top 60. Piercy missed the cut but slipped only one spot to No. 59. Even so, he had few complaints about his 69 to begin his bid for a record-tying third straight U.S. Open.
He turns 49 on Sunday. His first one was in 1992, when he made his professional debut with a 68 and was two shots out of the lead after the first round. "I'm right there. I feel like if I get off tomorrow to a good start, I'm right back into it". His goal is to hit the last one in four days. Dry does not mean a blue sky over the Pacific.
Schauffele, the 25-year-old San Diego native with the United Nations family tree who has rung up two seconds and four top 10s in only nine majors, wrung a gorgeous eagle with a stunning approach to nine feet after a hairy start on No. 18.
