Koepka struggles; holds off Johnson for PGA win

Brooks 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.
