Greenbrier Classic 2017: Xander Schauffele Wins 1st Career PGA Event

Xander Schauffele flashed his potential with a fifth-place finish at the U.S. Open. Less than a month later, the 23-year-old has won his first PGA Tour event.

Schauffele carded a three-under 67 on Sunday, finishing at 14 under overall and one stroke ahead of Robert Streb to win the 2017 Greenbrier Classic. Playing as part of the second-to-last group, Schauffele knocked his tee shot within three feet of the cup on the par-three 18th and tapped in to give himself the victory.

"I think it honestly just changed my life, really," Schauffele told reporters after the event. "I need a little bit of time to take it all in."

Streb missed a 26-foot birdie putt that would have sent the event into a playoff. He finished alone in second place at 13 under.

Jamie Lovemark and Sebastian Munoz tied for third at 12 under, while Kelly Kraft and Russell Henley rounded out the top five at 11 under.

Schauffele, who entered the day in third place, carded four birdies against one bogey in the final round. He opened the day with a birdie on No. 1 and added another on the par-three eighth to make the turn at two under. A bogey on No. 11 brought him back a stroke, but Schauffele got his first career win by closing strong.

He knocked down a clutch birdie putt from 12 feet out on No. 16 before putting things away with his tee shot on the 18th. When asked if his surprise finish at the U.S. Open played a factor in his calm nerves late, he was not shy about responding with the affirmative.

"The U.S. Open was a huge moment in my career," Schauffele said. "It was one of the biggest stages and for me to be calm and collected throughout the week and tie for fifth was huge for me mentally. It kind of gave me the confidence and allowed me to play and win this week."

The win moves Schauffele up to No. 27 in the FedEx Cup standings with the win. Darren Rovell of ESPN noted Schauffele made more with his win Sunday ($1.28 million) than he had his entire professional career coming into this week ($1.18 million).

Schauffele's only other professional win was at the 2015 Northern California Open.

Phil Mickelson, who struggled for most of the week, shot a six-under 64 on Sunday to finish in a tie for 20th place.

Davis Love III, who entered the day at 10 under, shot a five-over 75 to finish in a tie for 29th. He would have become the oldest winner in Tour history at 53.
