He finished fourth at the Zurich Classic of New Orleans, his best finish of the season. DeLaet satisfied the terms of his exemption in July 2012 with eight starts to spare and kept his Tour card. A fully recovered DeLaet started his season with a missed cut at the
Sony Open in Hawaii before making eight of his next nine through March, including two top-10s. He had a third-place finish at the

world ranking and finished 83rd. At
The Barclays, DeLaet had a career best PGA Tour finish of tied for 2nd with three other players, one stroke behind
Adam Scott. DeLaet climbed to 32nd in the world rankings at the end of the season. DeLaet's play during the 2013 season earned him a spot on the International Team for the
2013 Presidents Cup. DeLaet impressed captain
Nick Price posting a 3–1–1 record, paired with Australian
Jason Day for the first four sessions. DeLaet became just the second Canadian to play in the team competition, after
Mike Weir. DeLaet began the 2013–14 season with a missed cut at the
Shriners Hospitals for Children Open, but then finished T7 at the
CIMB Classic, T6 at the
WGC-HSBC Champions and T2 at both the
Farmers Insurance Open and the
Waste Management Phoenix Open. The remainder of DeLaet's season was not as successful. He missed the cut in the
Masters, the
U.S. Open and the
Open Championship. His 15th-place finish at the
PGA Championship was the high point for DeLaet's play in the majors. He finished the season with two second-place finishes, seven top-10 finishes, six missed cuts, and a WD at the
WGC-Bridgestone Invitational. In 2016, DeLaet qualified for the
2016 Summer Olympics in
Rio de Janeiro, marking golf's return to the Olympics for the first time since the
1904 Summer Olympics in
St. Louis. DeLaet represented
Canada. Canada was the defending nation of men's golf at the Olympics as
George Lyon won gold in 1904. As DeLaet represented the defending champion nation he was in the first group to tee off at the tournament. Shortly before the games began, his
caddie decided to not participate, prompting DeLaet to pick the recently retired
NHL player
Ray Whitney as his new caddie. DeLaet shot a 66 (5-under-par) in the first Olympic round ever on 11 August 2016, including 6 birdies and 1 bogey. He finished the tournament in 20th place. On 7 June 2022, DeLaet announced his retirement from professional golf and competing on the
PGA Tour. He cited ongoing back injuries as the reason for his retirement. == Awards and honors ==
