All of DeChambeau's irons and wedges are cut to exactly the same length: 37.5 inches (95.3 cm). Their lie and bounce angle are also the same; only the lofts are different. In addition to the single-length concept, his clubs are unusual for their extremely upright lie angle.  DeChambeau keeps the club on the same plane throughout his swing and does not turn his wrists during his swing. In 2011, at the suggestion of his instructor Mike Schy, DeChambeau switched to JumboMax Grips, the largest grips commercially available. The larger grips allow DeChambeau to hold the grips in his palms and not his fingers.
Lowry received his first call-up to the full Australia squad for a friendly against the Netherlands in Sydney and the Asian Cup qualifier against Oman in Melbourne in October. He did not play in either match. On 11 May 2010 he was selected as part of Pim Verbeek's 30-man provisional squad for the 2010 World Cup, and travelled to South Africa, but was not included in the final 23-man World Cup squad. Lowry was named in Han Berger's 18-man squad for an August 2010 friendly against Slovenia, but he did not appear in the match.
Fowler's first PGA Tour event as a professional was the Justin Timberlake Shriners Hospitals for Children Open where he finished tied for seventh. His second PGA Tour event was at the Frys.com Open played at Grayhawk Golf Club in Scottsdale, Arizona. He finished tied for second after losing to Troy Matteson in a three-way playoff that included Jamie Lovemark. Fowler's score of 18-under-par included a hole-in-one on the fifth hole in his final round. Fowler also notched an eagle in each of his four rounds.
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).
