Cantlay was named the PGA Tour's Player of the Year for the 2020-21 season after winning the BMW Championship and then the Tour Championship to claim the FedEx Cup. He also won the Memorial Tournament prior to the 2021 U.S. Open. The runner-up in the 2011 U.S.Amateur at Erin Hills and low amateur in the 2011 U.S. Open broke through for his first PGA Tour victory in the 2017 Shriners Hospital for Children Open in Las Vegas, and then added a second at the Memorial two weeks prior to the 2019 U.S. Open with a final-round 64. Cantlay nearly rallied to win the 2019 Masters, shooting weekend rounds of 64-68 to tie for ninth. Cantlay was a member of the 2011 USA Walker Cup Team. A week after his T-21 finish in the 2011 U.S. Open, Cantlay shot a course-record 60 during the PGA Tour's Travelers Championship at TPC River Highlands in Cromwell, Conn. It was the lowest round ever shot by an amateur in a PGA Tour event. He turned professional in 2012 as the No. 1 player in the World Amateur Ranking after tying for 41st in the U.S. Open at The Olympic Club, forgoing his final two seasons at UCLA. But back issues plagued Cantlay until 2017 when he managed to qualify for the season-ending Tour Championship after starting the year on a medical extension. He was a member of the victorious 2019 U.S. Presidents Cup and 2021 Ryder Cup Teams.
