Koepka held off a late charge from Dustin Johnson to win the PGA Championship for the second straight year.
Koepka took a seven-stroke lead into the final round at Bethpage Black and held on after Johnson cut his deficit to one stroke.
Koepka finished with a 4-over 74 to win by 2 strokes and claim his fourth major title. He joins Tiger Woods as the only golfers to win the PGA in back-to-back years since the tournament went to stroke play in 1958. Koepka has also won back-to-back U.S. Opens.
Koepka made bogey on four straight holes on the back nine, and when Johnson birdied No. 15, he had closed the gap to one stroke. But Johnson had back-to-back bogeys to restore Koepka’s cushion.
Johnson, the No. 1 player in the world rankings, shot 69. It’s the second straight major he’s finished as runner-up. Johnson, who was second to Woods at the Masters last month, has finished second in all four majors.
Johnson was putting together the best round of the day when he overshot the 16th green, leading to a bogey after he had birdied the 15th. His tee shot to the par-3 17th’s huge green wound up in the high rough, and he couldn’t sink an 18-foot putt for par. That left him three strokes behind his close friend and workout buddy.
