Was joint leader after three rounds of last year's U.S. Open at Torrey Pines, but in the end had to settle for a share of 13th place.
As an amateur he tied for 16th in the 2010 U.S. Open at Pebble Beach – unusually only good enough on that occasion to be joint low amateur with Scott Langley.
The University of Georgia student was named America’s outstanding college player that year and as well as earning a Walker Cup cap the following season – Jordan Spieth, Harris English and Patrick Cantlay were among his team-mates – he became only the second amateur to win a Nationwide Tour event.
Two years later he was the PGA Tour’s first debutant champion for 12 years with a victory at the Sony Open in Hawaii, which included three rounds of 63.
His second success came at the 2014 Honda Classic after a play-off with Rory McIlroy, Russell Knox and Ryan Palmer, then he tasted more success at the 2017 Shell Houston Open and this January was denied a fourth title when Hideki Matsuyama hit a 276-yard three-wood to three feet for eagle on the first hole of a play-off at the Sony Open.
