Bryson Dechambeau birdied the 18th hole to help stave off a comeback by the Canadian team and give the U.S. top honors at the World Amateur Team Championship.

Dechambeau's closing birdie, combined with Canada's Corey Connors making bogey from off the fringe on No. 18, proved to be the difference as the Americans won by two shots after entering the fourth round at Karuizawa Golf 72 East with a three-shot lead. Dechambeau, an All-American last year at SMU, shot a 73 after his record-breaking 61 in the third round, while Denny McCarthy added a 64 for the Americans. With each team counting only its top two scores, Beau Hossler's 75 was dropped.

This is the record 15th WATC title for the U.S., and their four-round total of 38-under 534 also set a tournament record. The score left them two ahead of the Canadians and three ahead of Spain, who were powered by a record-breaking individual performance from Jon Rahm. Rahm, a junior for Arizona State, closed with rounds of 62 and 67 and his 23-under 263 individual total broke the tournament record previously held by Jack Nicklaus, who shot a 269 at Merion in 1960.

Canada started the day six shots behind the Americans before staging a final-round comeback, with all three players shooting 70 or better. Adam Svensson set the pace with a 7-under 65, but it was Connors, a runner-up last month at the U.S. Amateur, who was the final player to finish. Needing a birdie on the final hole, his approach sailed long and lead to a three-putt, while Dechambeau hit his wedge approach to inside 10 feet to set up the decisive birdie.
