South Africa's Garrick Higgo stays steady to clinch second PGA Tour title

Dahmen seemed on course for victory heading down the stretch before nerves got the better of him. He bogeyed each of the last three holes, including a miss from three feet on the par-3 17th to ultimately close with a four-over 76.

All Higgo had to do was stay steady in the face of Dahmen's collapse, and not even a bogey of his own at 17 stopped him from taking the crown. 

The 25-year-old from Johannesburg was able to hold his never to make par on the 18th, closing with a level-par 72 to seal a one-stroke victory - his second on the PGA Tour following his victory at the Palmetto Championship four years ago.

"This is unbelievable and this is why I play the game. You know, the journey, I'm going to go through a down again, everybody does, I'm going to have ups. I just truly enjoy the journey," he said.

Dahmen was left to reflect on his disastrous finish, which he admitted was tough to take.

"I think I'm in a little bit of shock, honestly," he said. "It's not how you win a golf tournament, I'll tell you that. I don't deserve to win it. Bogeying the last three is inexcusable.

"This one could take a while to get over," he added. "It's one of those things, you learn more in defeat, unfortunately. This one's going to sting for a while."
