Koepka, whose caddie Ricky Elliott is from Portrush in Northern Ireland, becomes the seventh first-time major victor in succession, a run stretching back to Jason Day's victory in the 2015 US PGA Championship. On a day when Koepka overpowered this hay fever heaven with a final round 67 and equaled McIlroy's 72-hole U.S. Open scoring record, the Bulldog was arm-wrestling out of his class. It was an accomplishment that wasn't lost on golf's newest major champion, even if his father and other family members weren't in attendance at Erin Hills on Sunday and missed one of Koepka's appearances at a major for the first time. It was an especially good day for Spieth considering how the wind picked up at Erin Hills. "But there's way too many holes out here where one bad shot could be a double bogey quickly".
The week ended with 31 players under par, breaking the record of 28 at Medinah in 1990. It went from a good save and a tap-in par to now going 2-over through four and really behind the eight ball.
Brooks Koepka walked up to the eighteenth tee on Sunday afternoon with a comfortable lead over his nearest challenger, Brian Harman. He found stardom right at home as the U.S. Open champion. That tells you that he never followed up one mistake with another.
"Yeah, I've never been a big, big man in any sport I've played", he said. I felt he's been very unnoticed and maybe not respected as much as he should have for his record. "And it's no surprise". He was 100 feet away for birdie on No. 6 and burned the edge of the cup on that one, except that it ran by some 7 feet and he three-putted for bogey.
Fowler's seven birdies were from no more than 12 feet, including three in a row around the turn.
South Korea's Kim Si-Woo and Japan's Hideki Matsuyama were among five players on five under. But he started the day six shots out of the lead.
Koepka said a low moment occurred in 2012, as he prepared to sleep on the third-round lead of the Scottish Hydro Challenge.
"It was a long phone call for us - it was like two minutes", Koepka said.
But it made me feel a lot better seeing Brooks shoot 5-under.
Rickie Fowler s hopes of ending his wait for a major faded with an error-strewn performance, a level-par 72 leaving him six shots adrift.
Tommy Fleetwood's courageous bid faded as he finished alone in fourth on 11 under following a final round of 72, with Rickie Fowler, Bill Haas and Xander Schauffele a shot further back in fifth.
Brooks Koepka of the United States reacts after finishing on the 18th green during the final round of the 2017 U.S. Open at Erin Hills on June 18, 2017 in Hartford, Wisconsin.
Rickie Fowler said it was "fun" to play Erin Hills, which is an unusual descriptor for the U.S. Open. But the fairways were generous and the wind that serves as the course's best defense didn't kick up until the end. I'm sure Erin Hills and the USGA would like it to play firmer and faster to see what it would be like.
WICHITA, Kan. (AP) - Aaron Wise completed a wire-to-wire victory in the Air Capital Classic to lock up a PGA Tour card with his first Web.com Tour title.
"I am playing nicely and I have got the French Open, the Irish Open and the Open coming up in the next month. And I'll win if I stay patient and just keep doing what I'm doing". "I just couldn't stand the fact that I'd only won once". At 27, he'd won once on the PGA Tour and once on the European Tour.
He has been in this position before and in 2014 finished inside the top five of all of the majors, he had a chance at this year's Masters and came close again here at Erin Hills. More than worrying about the uncertainty of his career, he was trying to figure a way to close one of these big ones out.
It was an odd U.S. Open in this sense.
