The 118th U.S. Open Championship Shinnecock Hills Golf Club in NY has not been what we'd call player friendly.
The 28-year-old American fired a two-under-par 68 and with a one-over par total he won by one shot from Tommy Fleetwood, whose 63 equalled the championship's lowest round.
Koepka now joins Willie Anderson, John McDermott, Bobby Jones, Ralph Guhldal, Ben Hogan, and Curtis Strange as back-to-back winners of the U.S. Open.
Fleetwood has done well in the U.S. Open, finishing 27th in 2015 and fourth a year ago.
Koepka also crucially saved par on the 12th and 14th before striking the killer blow, a superb approach to the par-five 16th setting up a tap-in birdie.
Patrick Reed - The reigning Masters champion had been quiet since earning his first major win in April at Augusta National, but Reed surged up the leaderboard Sunday even getting to within one shot of Koepka's lead. Only the U.S. Open has struggled to present a fair championship and decently regulated course.
The tournament could have easily become a runaway win for Dustin Johnson, the world No. 1 who led by four strokes after 36 holes.
"I'm trying to choose my words because they play a fine line between guys teeing off in the morning being able to be really aggressive - a couple of 66s - and then making the course hard but just about on the edge (for the later starters)", said the Woburn attached golfer. Fleetwood missed an 8-footer for birdie on the 18th that would have given him the record for this tournament and tied the 62 Branden Grace shot in last year's British Open for lowest round in any major. He topped a tie for sixth by St. George native Jay Don Blake in the 1992 U.S. Open at Pebble Beach in California.
Tommy Fleetwood was surprised when he shot 66 in Friday's second round. "It's special to shoot a 63 at the US Open".
With Shinnecock Hills playing much easier than on Saturday, when it was a brutal test that the USGA admitted was unfair to the leaders, Koepka birdied the par-3 second to move to 2 over par. After Johnson's ball fluttered slightly on address at the fifth green, the USGA took seven holes to inform Johnson that its rules committee would "review" whether to asses him a penalty.
When they left the course, Finau and Berger both just hoped to be in the mix at day's end. Tony Finau and Daniel Berger started the weekend 11 shots out of the lead. Koepka was all over the pins early in the round, with birdies on three of the first five holes.
