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).
BMW Championship: At No. 22 in the FedExCup standings heading into the third Playoffs event, the BMW Championship, he bogeyed No. 17 in a final-round even-par 72 to miss advancing to the TOUR Championship by half a point, finishing the season No. 31 in the FedExCup standings. Charl Schwartzel fired a final-round 8-under 64 to claim the No. 30 position.
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.
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.”
Lowry made his debut for the Glory on 30 January 2016, starting against Melbourne Victory. Lowry then scored his first Perth Glory goal on 20 February 2016 when he scored a header in the 41st minutes, to give Brisbane Roar a thrashing with a 6–3 win for Perth Glory. Throughout the 2015–16 season, Lowry established himself in the starting eleven and formed a central defense partnership with Alex Grant, as he made ten appearance for Perth Glory in his first half of the season.
