It turned out to be a closer finish than most expected but Brooks Koepka has won the PGA Championship, making it four major titles in less than two years time.

Koepka wins the PGA in back-to-back years and now becomes the #1 ranked golfer in the world.

He squandered a seven shot lead at the start of the final round. Dustin Johnson climbed to within one stroke but then he faltered.

Koepka's 4-over-par 74 was enough to finish 8-under-par and win the PGA title wire-to-wire.
