Immediately after the Masters in mid-April 2016, DeChambeau turned professional and signed a long-term agreement with Cobra-Puma Golf. He made his pro debut days later at the RBC Heritage in South Carolina and tied for fourth, earning over $259,000. The decision to turn professional meant the forfeiture of his exemptions to the U.S. Open at Oakmont and Open Championship at Royal Troon; he qualified his way into the U.S. Open, tied for fifteenth place for over $152,000, and improved his world ranking to 148.

On 27 January 2016, Lowry returned to Australia after a decade away from Australia when he signed a two-and-a-half-year deal with A-League side Perth Glory. Upon joining Perth Glory, Lowry said of the move, quoting: "I've got a lot of experience behind me now and I want to use it to guide the young lads who are in this young squad. I've spent 11 years in England and it's shaped my football over there and I'm really happy to be here and get stuck into the games"
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.
On June 16, Fowler carded a round of 65 at Erin Hills to take the first round lead at the 2017 U.S. Open. Fowler equaled the lowest first round score at the U.S. Open and led by one stroke from Paul Casey and Xander Schauffele. He followed this up with a one over par 73 in the second round to fall out of the lead by one stroke, held by four other players. He shot 68-72 over the weekend to finish in a tie for fifth place. This gave Fowler his sixth top-5 finish in a major, but he is still yet to win. Fowler started the PGA Championship with a 2-under 69 which was two strokes behind the leaders. After rounds of 70-73, he closed out the year's last major with a 4-under 67, including a run of four consecutive birdies on holes 12 through 15. Despite his solid finish, Fowler ended up tied for fifth and was 3 strokes behind the winner, and friend, Justin Thomas. It was his seventh top-5 major finish, meaning he's had multiple top-5 finishes at every major.
In July 2011, Fowler tied the 54-hole lead at the AT&T National, but an early double bogey on Sunday derailed his opportunity for his first PGA Tour win. Two weeks later Fowler finished tied for 5th in The Open Championship at Royal St George's. In August, Fowler finished in a tie for second at the WGC-Bridgestone Invitational behind winner Adam Scott, lifting him to 28 in the world rankings.
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 PGA Championship, Fowler carded 74-69-75-68 to finish with a six-over par total of 286, in a tie for 51st place. Early on the third day Fowler rocketed up the leaderboard with three birdies in the first five holes only to falter later in the round with two triple bogeys, effectively ending his hopes of a first major championship and PGA Tour win.
Lowry made his Leyton Orient debut, playing as a left-back position, in the opening game of the season, which saw Leyton Orient lost 2–1 to Chesterfield. Since his debut, Lowry established himself in the left-back position in the first half of the season despite being sidelined with suspension and fitness concern that saw him out for two matches. Following his return to the first team, Lowry played in the central-defense between December and March until he dropped from the first team throughout March. Lowry went on to make his first team return throughout 2014–15 season, making thirty-four appearance in his first season at Leyton Orient.
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.
As for the workouts he’s doing, DeChambeau is continuing work he’s done with Greg Roskopf, whose system focuses on making people stronger where they are weak, particularly at extraneous points in their muscular system. In other words, there are likely points in the golf swing — in various golf movements — where DeChambeau isn’t as strong as he could be, hence the more work and weight. If he has already ascended to 220 in a matter of weeks, 230 should follow soon. Stay tuned.
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.
