Woodland played conservatively down the 18th and made one last birdie that only mattered in the record book. He finished at 13-under 271, one shot better than Tiger Woods' historic rout in 2000. The difference was Woods won by 15 shots and was the only player under par. With a marine layer blocking the sunshine, and no significant wind at Pebble Beach all week, 31 players finished under par.
Koepka closed with a 68 for his second runner-up in the majors this year, along with his second straight PGA Championship title.
Justin Rose was the only one who caught Woodland, with a birdie on the opening hole. Rose bogeyed from the bunker on No. 2, and fell out of the race with three bogeys in a four-hole stretch on the back nine. He shot 74 and shared third with Xander Schauffele (67), Jon Rahm (68) and Chez Reavie (71).Woods birdied six of his last 12 holes and was never a factor.

In the last two U.S. Opens at Pebble Beach, only one player — Tiger Woods in 2000 — finished under par.
Woodland was at 11 under entering the final round, one shot ahead of Justin Rose. Twenty-six players began the final round under par.
Woods won in 2000 at 12 under, 15 shots better than anyone else. He was off to another rough start with two bogeys in two holes.
