Golf is not a game designed to be played well over an extended period of time. Of course, there are exceptions (Tiger Woods in his prime comes to mind). For three rounds at the Greenbrier Classic, Sebastian Munoz looked like just such a dominant force.

Then the putter that powered his 54-hole dominance deserted him on Sunday. Bogeys on four holes of The Old White TPC course in White Sulphur Springs, W.V. unraveled his game, ultimately dropping Munoz to third place.

Xander Schauffele and a corps of at least five Tour pros waged a battle for supremacy all afternoon. Schauffele was infused with confidence after a fifth-place finish at the U.S. Open at Erin Hills.

The first-time winner on the Tour calmly drained his putt on the 18th green to card a 14-under par 266. It was enough for a slim one-stroke victory over Robert Streb.
