DeChambeau made his PGA Tour debut as an amateur in June 2015 at the FedEx St. Jude Classic near Memphis, Tennessee, and finished in 45th place. He played in his first major championship at the U.S. Open at Chambers Bay, but missed the cut by four strokes. DeChambeau was unable to defend his NCAA title in 2016 after the SMU athletic department was handed a postseason ban by the NCAA. He decided to forgo his senior season to play in a number of events before turning professional. At the 2015 Australian Masters in November, DeChambeau was runner-up with John Senden and Andrew Evans, two shots behind the winner Peter Senior. He was the low amateur at the Masters in 2016 and tied for 21st place.
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.
THE PLAYERS Championship: After beginning the final round of THE PLAYERS Championship three strokes off the lead, at 7-under 209, played his last six holes in 6-under to post a 6-under 66 and join a three-hole aggregate playoff with 2008 PLAYERS champion Sergio Garcia and Kevin Kisner. Finished birdie-par-birdie-eagle-birdie-birdie on Nos. 13-18 in regulation. Played Nos. 15-18 in a 5-under total of 11 strokes. The four-hole score of 11 set a new single-round low for the final four holes at TPC Sawgrass. Previously, seven players had finished with a score of 12 on the final four holes. When Garcia was eliminated after the aggregate playoff, Fowler and Kisner returned to the famed, par-3 17th for sudden death. Fowler converted a 4-foot, 8-inch putt for birdie to claim the title. Before his back-nine charge, his mother had made her way to the airport to leave town. A text message alerting her to her son's rally resulted in her immediate return to TPC Sawgrass in time to witness the win. With the victory, moved to ninth in the Official World Golf Ranking and No. 7 in The Presidents Cup standings.
Fowler has three tattoos. One is a block "G" near his left elbow in honor of Georgia Veach, the daughter of a Seattle pastor and friend. Georgia was diagnosed with lissencephaly. Fowler got the tattoo just before the 2015 Presidents Cup. The second is from January 2016 and contains the name Yutaka Tanaka (Rickie's grandfather) in Japanese script on his left biceps. The third tattoo came just weeks after playing at the 2016 Summer Olympics and is of the Olympic symbols.
Waste Management Phoenix Open: Two weeks after the win in Abu Dhabi, made his eighth consecutive start in the Waste Management Phoenix Open, where he found himself three strokes off the lead after 54 holes. A final-round 4-under 67, capped off by a clutch birdie on the 72nd hole, forced sudden death with Hideki Matsuyama. On the fourth extra hole, the par-4 17th, an errant tee shot found the water hazard for the second time of the day. Matsuyama made par to win. Ranked second in Strokes Gained: Tee To Green and T1 in Strokes Gained: Total at TPC Scottsdale.
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.
On 23 November 2011, Lowry was again loaned out to play in the Championship, this time to Millwall until 3 January 2012. He followed Aston Villa team-mate Nathan Baker who also signed on loan for Millwall two days earlier. Lowry made his Millwall debut three days later, where he played 90 minutes, in a 0–0 draw against Crystal Palace. His impressive display at Millwall soon earned a loan extension. Weeks later on 13 January 2012, Lowry was sent-off in the 22nd minutes after stamping on Nikola Žigić, which saw Millwall lose 6–0. Three years on after signing for Birmingham City, Lowry stated, quoting: "Whatever club I play for I fully commit to that club at the time. I play with my heart on my sleeve. Sometimes in the past I have gone overboard but I was a younger player then, I have learned a lot from these types of experiences. But I am an aggressive player, that’s the way I like to play and I can’t change the way I play. I will use my experience now and be a bit more clever."'
Deutsche Bank Championship: Shot a final-round 3-under 68 to come from one shot back and defeat third-round leader Henrik Stenson at the Deutsche Bank Championship, good for his third career PGA TOUR victory. Earned the win at age 26 years, 8 months, 25 days in his 150th career start. Collected 2,000 points and moved from No. 22 to No. 3 in the FedExCup standings.

Aberdeen Asset Management Scottish Open: Earned his second international victory when he captured the Aberdeen Asset management Scottish Open in come-from-behind fashion at Gullane GC in July. After a bogey on the 14th hole Sunday, fell two shots off the lead. He responded with three birdies over his final four holes to catch and pass American Matt Kuchar, who shot a final-round 68 to post the clubhouse lead at 11-under. He made a 9-foot birdie putt at No. 15, made a two-putt birdie at the par-5 16th, parred the 17th then hit his approach shot on the par-4 finishing hole to 2 feet for the tap-in birdie and the title. Joined seven other players who made the Scottish Open their first European 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.
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 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.
