First round Thursday, June 14, 2018 Conditions were extremely difficult as gusty winds hung around all day with sunny skies, making the course firm and fast. Only four players broke par, including
Dustin Johnson, one of the tournament favorites. The scoring average for the round was 76.47.
Second round Friday, June 15, 2018 Dustin Johnson held the lead after shooting a 67, four shots ahead of
Charley Hoffman and
Scott Piercy. Scoring conditions got more difficult as the day went on. Koepka's two-over 72 was the lowest score among the final four groups. Only three rounds in the 60s were recorded, two of them by Berger and Finau. The scoring average for the round was 75.3.
Phil Mickelson incurred a two-shot penalty on the 13th when he walked after his ball which was running slowly away from the hole after his putt and deliberately hit the ball backwards towards the hole while it was still moving. He ended up shooting 81 (+11), equalling his highest score at the U.S. Open. Fleetwood shot the sixth round of 63 in U.S. Open history to finish in second. He began the round six behind and began by sinking a putt from at the 2nd and three more birdies on the front-nine. He made four straight birdies on holes 12–15, with putts of at 12, at 14, and at 15. Fleetwood had an eight-foot putt at the 18th for the first 62 in U.S. Open history, but it slid past the hole that would have forced the first two-hole playoff. Johnson made birdie at the 5th but three-putted for bogey at the 7th, 11th, 14th, and 17th. He birdied the last to shoot an even-par 70 and finish two shots behind Koepka. Finau bogeyed three of his first four holes but got back to even for the round with a 26-foot birdie at the 11th. He came to the 18th two back of Koepka but made double bogey and ended up in fifth place, four behind. Berger also started his round with two bogeys and finished with a three-over 73 to tie for sixth.
Patrick Reed began three shots behind but birdied his first three holes and five of the first seven to tie for the lead. He made four bogeys the rest of the round, however, to fall back to fourth place. With the win, Koepka becomes the seventh player to win consecutive U.S. Opens, and the first since
Curtis Strange in
1989.
