THE PLAYERS Championship: A week after collecting his first PGA TOUR victory, nearly became the first player since David Duval (1997) to post first two TOUR victories in back-to-back weeks, finishing T2 at THE PLAYERS, two strokes behind winner Matt Kuchar. Holed a birdie attempt from 21 feet, 7 inches on the par 3 17th in the final round to move to 11-under but couldn't convert a 7-foot, 7-inch birdie on No. 18 that would have given him the clubhouse lead at 12-under. Recorded his fifth career runner-up finish on TOUR in his 73rd start. His T2 performance came in his third start at THE PLAYERS and first in which he made the 36-hole cut. Moved into contention with a 66 in the third round, a career low at TPC Sawgrass. Entered the final round three shots off the 54-hole pace.
Frys.com Open: At the Frys.com Open in Scottsdale, Ariz., reached a three-way playoff with Jamie Lovemark and eventual-winner Troy Matteson. Began the final round four strokes behind Matteson, but played his first five holes in 5-under, punctuated by a hole-in-one from 211 yards at the par-3 fifth hole. After finishing T2 in the playoff, he had recorded all eight of his professional rounds in the 60s. Thanks to the T7 in Las Vegas at the Justin Timberlake Shriners Hospitals for Children Open and T2 finish at Grayhawk GC, he surpassed No. 150 from the 2008 money list, earning special temporary membership on TOUR for the remainder of the season.
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).
The Open Championship: Playing in the final group Sunday for the second straight time in a major championship, made a solid bid for the title, at The Open Championship, with a final-round, 5-under 67. Along with Garcia, finished second to Rory McIlroy by two strokes. With his finish at Royal Liverpool GC, became the only player of the season to claim top-five finishes in the year's first three major championships. He also became the first player to claim top-10 finishes in a season's first three majors since Woods achieved the feat in 2005. His T2 at Royal Liverpool supplanted his previous-best Open Championship finish (in four starts) of T5 in 2011. Rounds of 69-69-68-67 made him the only player in the field to post all four rounds in the 60s.
At the 2016 U.S. Open at Oakmont Country Club near Pittsburgh, Lowry shot 65 (−5) in the third round for 203 (−7) and a four-stroke advantage over Dustin Johnson and Andrew Landry at the 54-hole stage. The 65 was Lowry's joint career best round at a major championship. Due to weather delays on Thursday, the third round was not completed until early on Sunday, and Lowry birdied two of his remaining four holes to extend his two stroke overnight lead to four. In the final round he was in contention for the title, within one shot of Dustin Johnson after 12 holes, before three consecutive bogeys on holes 14, 15 and 16 ended his chances. He finished the tournament tied for second place, with a final round score of 76.
After a T-12 finish at the Masters, Fowler earned his first win in over three years with a playoff victory at The Players Championship in May. Trailing Sergio García midway through the final round by five shots, Fowler played the final six holes in 6-under par, including an eagle at the par-5 16th. After a birdie at the famous 17th hole, Fowler's final birdie of the round on 18 left him at 12-under par. Both García and Kevin Kisner had birdie attempts to win at the 18th in regulation, but both missed and the three men went to a three-hole aggregate playoff to decide a winner on holes 16–18. Fowler and Kisner went par-birdie-par to tie at −1 while García's three pars left him at even and he was eliminated. Thus Fowler and Kisner went to sudden death starting at the 17th, where Kisner's tee shot landed within about 12 feet (3.7 m) of the cup. Fowler answered with a shot inside of five feet, and when Kisner's birdie attempt slid by, Fowler responded by making his short birdie to claim the championship. Fowler played his final 10 holes in 8-under par. On July 12, he won the Aberdeen Asset Management Scottish Open on the European Tour, shooting a 12-under-par 268. On September 7, he won the Deutsche Bank Championship, the second FedEx Cup Playoffs event, by one stroke over Henrik Stenson, for his third victory on the PGA Tour.
On July 16, 2017, DeChambeau earned his first PGA Tour victory by winning the John Deere Classic by a single stroke over Patrick Rodgers. He carded a round of 65 in the final round to win his maiden title in his 40th start on tour. 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).
