Played in the final pairing with third-round leader Anthony Kim at The Greenbrier Classic. Trailed by one at the beginning of the day and fell further behind with a 4-over 38 on his opening nine holes. Stormed back with six birdies on the final nine for a 1-under 69, placing him in his first career playoff, with Bob Estes and Bill Haas. Just a few minutes after making a birdie on the par-3 18th hole to finish 10-under, he sprinted to the tee box of the first extra hole (high-fiving fans along the way) before a perfectly struck 9-iron left him within 10 feet of the hole, which he calmly knocked in for his first win in his 21st start on the PGA TOUR. Became the TOUR’s sixth rookie winner of the season—the most since 1970-and the 10th first-time winner. The victory was the 12th of the season by a player under age 30 and earned him an invitation into the following week’s World Golf Championships-Bridgestone Invitational.
