100^th PGA Championship

Brooks Koepka held off the challenges of a resurgent Tiger Woods and Adam Scott to win his second Major of the season at the US PGA Championship.

The two-time defending US Open champion entered day four with a two-shot lead and that was how he ended it but that did not tell the story of a dramatic afternoon at Bellerive Country Club.

Koepka was caught by defending champion Justin Thomas on the front nine and Australian Scott on the way home but kept his cool to record birdies on the 15th and 16th and sign for a 66 to get to 16 under.

Woods' 64 was his lowest ever final round in a Major and a birdie on the last moved him one shot ahead of Scott who finished at 13 under.

Spaniard Jon Rahm and American Stewart Cink were then five shots behind the winner, one clear of Thomas, Open champion Francesco Molinari, Belgian Thomas Pieters and another American in Gary Woodland.

The victory for Koepka means he is the first man to win the US Open and US PGA Championship in the same year since Woods achieved the feat in 2000 on his way to the 'Tiger Slam', and only the fifth person to do it in history.

The 28 year old's stunning season is all the more remarkable considering he did not play any events between the first week in January and last week in April due to a wrist injury.

"When I look at what I've done in the past two months, it's incredible," he said. "Looking where I was, sitting on my couch watching the Masters, and to think I would do this, I would have laughed at you and told you there was no way, no chance, and to do it is really incredible.

"I think sitting on the couch made me really appreciate how much I actually love this game and love competition.
