Began that year on a medical extension, but made it through the FedEx Cup play-offs to the Tour Championship. His best major display came at the 2016 US Open, where he tied for second behind Dustin Johnson, and he was also runner-up to him two weeks later at the WGC-Bridgestone Invitational, rising to a career-high 25th in the world as a result.
The former San Diego State University student's maiden Tour success came at his home state Reno-Tahoe Open in 2011 - he shot 61 in the third round - and the following season he captured the RBC Canadian Open, where he began with a 62 and tied the circuit's oldest 72-hole scoring record.
He was then one of four runners-up behind Ian Poulter in the 2012 WGC-HSBC Champions event in China and in 2013 tied for fifth at the PGA Championship thanks to a closing 65. In May tied for second at the AT&T Byron Nelson behind Sunghoon Kang three weeks after finishing third at the RBC Heritage.
