On holes 11 and 12, after getting himself into tough predicaments he came through with bogey and par saves, respectively, to help him stay atop the leaderboard.
A year after shooting 16 under to win at Erin Hills by four strokes, Koepka repeated in the challenging conditions at Shinnecock. He's one of the best to ever play the game.
Fleetwood also shot a stunning 63 in Sunday's final round of the 118th US Open, agonisingly missing from eight feet for birdie on the 18th to equal the all-time major record of 62 set by Branden Grace in last year's Open Championship at Royal Birkdale.
His 63 was the sixth in U.S. Open history and just the second in a final round.
"I don't think I could have dreamed of this, going back-to-back", Koepka said when interviewed by odd on the 18th green.
Playing in the next-to-last pairing with Dustin Johnson, Koepka began the round in a four-way tie for the lead with Johnson, Daniel Berger and Tony Finau. The signature moment from this U.S. Open was a trio of putts to escape trouble on the back nine? two for par, one for bogey.
"When something like (Saturday) happens, all of a sudden you're coming into today, you knew that they were going to water the heck out of the greens, that they're going to be soft", Reed said.
He recovered with three fantastic rounds, however, and the putts the he holed down the stretch on the final day to retain his title by two shots showed great courage.

Nigeria vs Iceland : Musa brace restores hope for Eagles
Iceland had a chance to get one back but Gylfi Sigurdsson sent a penalty kick way over the Nigeria bar in the 83rd minute. Nigeria sweep aside Iceland to set up showdown with Argentina after Ahmed Musa strikes twice against Iceland .
So, in the end, Shinnecock prevailed again, pretty much fairly this time - though visions of 2004's asphalt-like greens danced in some players' heads on Saturday.
He hung around playing partner and friend Brooks Koepka most of the round but every time Koepka made a big putt it seemed Johnson would miss one right after.
The world number one double-bogeyed the second and dropped another four shots before the turn to slip back to two over before making a first birdie at the 11th in Long Island, where lightning quick greens and pin placements were causing all sorts of problems.
"I've worked with him for the last five years and he's been like that all that time". I've got to be competing at something. "I was hitting the ball well and I was putting the ball well, but I just had to keep going".
To call the U.S. Open a fiasco this year would be kind. We're extremely close. I love the guy to death.
There's no doubt now, however, that Koepka is back, and he has proved his major mettle on the toughest test the US Open can offer.
A hot putter kept him in front as he made clutch pars at the next three holes. "That was a huge difference that got him back in this championship", Paul Azinger said on FOX. Fowler was 19 shots better than his 84 in the third round, the highest score in his U.S. Open career. There definitely will be one more major at least.
With scores fluctuating on a round-by-round basis, Johnson's differential between the second and third round was 10 shots - 67 on day two followed by a 77 yesterday.
