The Honda Classic: After beginning the final round of The Honda Classic with a four-stroke lead, posted a 1-over 71 to win by the same margin for his fourth career PGA TOUR title. It marked the first of five 54-hole leads he converted to victory. Opened with back-to-back 66s for the second consecutive year and posted a 65 in the third round to post the best 54-hole total since the event moved to PGA National in 2007 at 13-under 197. Seized the 54-hole lead with the widest margin of his career entering a final round. Turned in 2-over 37, but posted three birdies on the back nine to take command of the tournament. Despite bogeys on the 71st and 72nd holes, claimed his first victory since the 2015 Dell Technologies Championship. Finished the week second in Strokes Gained: Putting (7.392) and moved to 10th in the FedExCup standings and ninth in the Official World Golf Ranking, his first time in the top 10 since the 2016 BMW Championship.
Some modern pros, including Woods, have caught flak for working out too hard and wearing down their bodies. For DeChambeau, the philosophy is the exact opposite: His gym inspiration is to stave off a nagging back injury. That injury — which DeChambeau says stems from a childhood trampoline accident plus the wear of hitting nearly infinite range balls — left him in major pain last season. “Sleeping hurt, everything hurt,” he said. “But it’s pretty cool what you can do to the body by working out. Most people say, ‘okay, I just have to sit down and rest, I’ve gotta take time off,’ but I’ve tried that route and I’ve realized that actually makes you worse.”
In 2008, Fowler repeated as Sunnehanna Amateur champion. In the first round of the U.S. Open, Fowler shot a −1 (70) and was in a tie for 7th place. He was one of three amateurs to make the cut, along with Derek Fathauer and Michael Thompson. He ended the tournament tied for 60th. In October 2008 Fowler played on the Eisenhower Trophy team that finished second. He was the leading individual player.
Nationwide Tour Players Cup: Playoff runner-up to Derek Lamely at the Nationwide Children's Hospital Invitational. Started the final round five shots behind 54-hole leader Dave Schultz. Held the lead during much of the final round but suffered a bogey at the 72nd hole of regulation to drop into a tie with Lamely and force a playoff. Lost to Lamely when he failed to get up and down from a greenside bunker on the second extra hole, missing his par putt of 12 feet. Lamely rolled in a three-foot par putt to win.
Lowry made his professional debut in the 2009–10 UEFA Europa League in an away fixture at Rapid Vienna. On 17 September 2009, Lowry signed a three-month loan deal with Football League Championship side Plymouth Argyle. Lowry made his Plymouth Argyle debut on 19 September 2009, playing 90 minutes, in a 3–1 loss against Newcastle United. He played 13 league games for Plymouth during his loan spell, where he impressed many and was recalled by Villa who required Lowry's services as cover after some injuries to defenders.
In June 2015, he became the first SMU Mustang to win the NCAA individual championship, recording a score of 280 (−8) to win by one stroke. In August, he won the U.S. Amateur title, defeating Derek Bard 7 & 6 in the 36-hole final. He became the fifth player to win both the NCAA and U.S. Amateur titles in the same year, joining Jack Nicklaus (1961), Phil Mickelson (1990), Tiger Woods (1996), and Ryan Moore (2004).
In September, he signed a clothing deal with Puma. In the same month, he was also chosen as a captain's pick for the U.S. Ryder Cup team. At age 21 years and 9 months when the matches began, Fowler became the youngest U.S. Ryder Cup player of all time, and only European Sergio García was younger when he made his Ryder Cup debut in 1999. Fowler forfeited a hole during foursomes competition on the first match day because of a rules violation, by taking a permissible free drop from muddy conditions in an improper location, a mistake U.S. captain Corey Pavin attributed to Fowler's inexperience. On the final day of the competition in his singles match against Edoardo Molinari, Fowler birdied the last 4 holes to halve the match after having been 4 down after 12 holes.
On July 16, 2017, DeChambeau earned his first PGA Tour victory by winning the John Deere Classic by a single stroke over Patrick Rodgers.

The win coming the week before, gained DeChambeau a place in the 2017 Open Championship, where he missed the cut after rounds of 76–77 (+13).
