FARMINGDALE, NY — Brooks Koepka took his place in PGA Championship history with a wire-to-wire victory, minus the style points.

In a raging wind that turned Bethpage Black into a beast, Koepka lost all but one shot of his record seven-shot lead Sunday. He lost the brutal Long Island crowd, which began chanting "DJ!" for Dustin Johnson as Koepka was on his way to a fourth straight bogey.

But he delivered the key shots over the closing stretch as Johnson faded with two straight bogeys, and Koepka closed with a 4-over 74 for a two-shot victory and joined Tiger Woods as the only back-to-back winners of the PGA Championship since it went to stroke play in 1958.

Koepka said at the start of the week that majors are sometimes the easiest to win.

This one should have been. It wasn't.

His 74 was the highest final round by a PGA champion since Vijay Singh won in a playoff in 2004 at Whistling Straits.

"I'm just glad I don't have to play any more holes," Koepka said. "That was a stressful round of golf. I'm glad to have this thing back in my hands."

Johnson now has runner-up finishes in all four of the majors, the wrong kind of career Grand Slam.

"I gave it a run," he said. "That's all you can ask for."

Koepka returned to No. 1 in the world with a performance that defines his dominance in golf's biggest events.

He becomes the first player to hold back-to-back titles in two majors at the same time, having won a second straight U.S. Open last summer 60 miles down the road at Shinnecock Hills. He was the first wire-to-wire winner in the PGA Championship since Hal Sutton at Riviera in 1983.

WEB.COM TOUR Robby Shelton got up-and-down from a bunker to save par on the 18th hole Sunday for an even-par 71, giving him a one-shot victory in the Knoxville Open and his second Web.com Tour victory of the year.

Shelton started the final round at Fox Den Country Club with a two-shot lead and fell behind early with consecutive bogeys as Zhang Xinjun made two early birdies. Shelton started the back nine with back-to-back birdies to regain control.

Mark Anderson began the back nine with an eagle and finished with a birdie and a 68, making Shelton finish with par for the wind.

Shelton finished at 15-under 269.

He won two weeks ago in the Nashville Golf Open, and this victory enabled him to take over the lead from Zhang on the Web.com Tour points list. The top 25 earn PGA Tour cards at the end of the regular season.

Zhang (70), Tim Wilkinson (70) and Mark Hubbard (71) tied for third.
