Koepka, who won the 2017 edition at Erin Hills by four shots with a tournament total 16-under par, became the first back-to-back US Open victor since Curtis Strange successfully defended his title in 1989.
"Everyone said Erin Hills was set up for me".
Brooks Koepka has grown used to people underestimating him, but after flying under the radar to win a second straight U.S. Open title he would not have it any other way.
Even after the USGA Chief Executive Mike Davis came on the air late in the afternoon to admit the association made a few mistakes and allowed good shots to be penalized, it isn't clear that they really know where the line between hard and unfair really lies.
Facing a course setup and weather conditions that were far more docile than in Saturday's third round, Koepka moved to the front quickly by birdieing three of the first five holes.
He also made an incredible 55-foot putt for a birdie at the second. "He's able to dismiss whatever has happened before nearly instantly", he added.
The 28-year-old closed with two-under par 68 to become just the seventh back-to-back victor and the first since Curtis Strange in 1988-89.

The " Fixer Upper " couple have announced the arrival of their fifth child , a baby boy. In March, the HGTV stars announced they were expecting a baby boy.
"We didn't really speak too much, " Koepka said. "He is very talented and believed in himself [at Shinnecock Hills]". "Shinnecock Hills is handsome, but unfortunately, they've lost the golf course", Johnson said in an interview with Sky Sports. "I was hitting the ball well and I was putting the ball well, but I just had to keep going. It would have been fun to dual it out with him coming down the end, having to make some putts". He made eight birdies - none on the two par-5s - and missed an 8-foot birdie putt on the final hole for a 63, only the sixth player in US Open history to go that low. I just feel like I need to be back out grinding.
The world number one was one of the early starters on the second day of competition and was looking to assume the outright lead, having shared it with three other players overnight.
But a costly three-putt bogey on the par-4 9th hole would be the start of an unravelling. He entered the final hole in third place.
Johnson and defending champion Brooks Koepka will be right behind them.
"It's what we practice for and I believe in myself".
"You were seeing shots that were well played and not rewarded", said Mike Davis, the chief executive of the USGA. At the time Fleetwood posted, Koepka was 1 over and had to preserve par over 12 holes to maintain his lead. We're extremely close. I love the guy to death.
"It won't be necessarily the golf course itself; the conditions can obviously create scores similar to what the U.S. Open just saw, but I thoroughly enjoy links golf". It was great to get it going on the back nine.
