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.[65] He did not play in either match.[66][67] On 11 May 2010 he was selected as part of Pim Verbeek's 30-man provisional squad for the 2010 World Cup,[68] and travelled to South Africa, but was not included in the final 23-man World Cup squad.[69] 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.[70][71]
Lowry elected to turn professional the week after his Irish Open triumph, meaning that he would miss out on the opportunity to play in the Walker Cup in September 2009.[11] He made his professional début on 28 May at the European Open, where he shot 78 in the first round to end the opening day almost at the back of the field, and went on to miss the cut following a second round 73.[12]
BMW Championship: After entering the final round of the BMW Championship in a second-place tie with Jason Day (five strokes behind Marc Leishman), recorded a 4-under 67 to finish T2, his 11th career runner-up on the PGA TOUR. Week was highlighted by a career-best, six consecutive birdies in the first round on Nos. 12-17. Chipped in from 64 feet on the 17th.
Lowry did not win on the European Tour from 2016 to 2018 but was joint runner-up in the 2017 DP World Tour Championship, Dubai and runner-up in the 2018 Andalucía Valderrama Masters. In January 2019 he won the Abu Dhabi HSBC Championship by a stroke from Richard Sterne. Lowry led by 3 strokes after three rounds but was two-over-par after 11 holes of his final round and dropped 4 shots behind Sterne. However he finished with 3 birdies in the final 7 holes, while Sterne had two bogeys, giving Lowry the victory.[20]
In 2008, Fowler repeated as Sunnehanna Amateur champion. In the first round of the U.S. Open, Fowler shot a −1 (70) and was in a tie for 7th place. He was one of three amateurs to make the cut, along with Derek Fathauer and Michael Thompson. He ended the tournament tied for 60th. In October 2008 Fowler played on the Eisenhower Trophy team that finished second. He was the leading individual player. 

Born in Modesto, California, to John Howard Aldrich DeChambeau and Janet Louise Druffel, DeChambeau moved to Clovis, east of Fresno, at age seven. He attended Clovis East High School and won the California State Junior Championship at age 16 in 2010. DeChambeau graduated in 2012 and accepted a scholarship to Southern Methodist University in Dallas, Texas, majoring in physics.
Fowler's first PGA Tour event as a professional was the Justin Timberlake Shriners Hospitals for Children Open where he finished tied for seventh.[8] 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.[9]
Abu Dhabi HSBC Golf Championship: Held off final-round charges from Thomas Pieters, Rory McIlroy and Henrik Stenson to win the Abu Dhabi HSBC Golf Championship, marking his second European Tour title. The victory was the first at the event by an American since Chris DiMarco won the inaugural event in 2006. Final-round highlights included a holed bunker shot on the eighth hole (which helped propel him to a three-stroke cushion at the turn), a chip-in for birdie on the 17th hole and then a par on the last to hold off Pieters by one stroke.

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.


Nationwide Tour Players Cup: Playoff runner-up to Derek Lamely at the Nationwide Children's Hospital Invitational. Started the final round five shots behind 54-hole leader Dave Schultz. Held the lead during much of the final round but suffered a bogey at the 72nd hole of regulation to drop into a tie with Lamely and force a playoff. Lost to Lamely when he failed to get up and down from a greenside bunker on the second extra hole, missing his par putt of 12 feet. Lamely rolled in a three-foot par putt to win.
Quicken Loans National: Starting the final round of the Quicken Loans National seven shots back, the Quicken Loans ambassador recorded a career-best nine birdies to post his low round of the week, a 5-under 65 to finish T3. Marked his third top-five in his last four starts. Chances for victory took a serious hit with a double bogey (the only one of the final round) on No. 14, the easiest hole in the final round. Marked second top-three finish in six starts at the Quicken Loans National (2015-2nd).
PGA Championship: Finished T3 and two strokes behind McIlroy at the PGA Championship in his 20th major championship start, with T19 in 2013 the previous-best finish in four prior PGA Championship starts. Became the first to claim top-five finishes in all four majors since Woods in 2005. Since 1934, is just the third player to perform the feat, joining Woods in 2000 and 2005 and Jack Nicklaus in 1971 and 1973. Played all four majors in 32-under, with McIlroy second on the list, at 27-under.
After Lowry's loan spell at Leeds was coming to an end, on 11 May he signed a new two-year contract extension at Aston Villa. It was a remarkable few days for Lowry, he was promoted with Leeds, received a call up to Australia's World Cup Squad and on the same day he signed a new two-year deal with Villa.[15] Despite signing a contract with the club, Leeds United was considering re-signing him for the second time ahead of the 2010–11 season, but never happened.[16]
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 missed the first three cuts of his professional career, but had his first payday on 5 July, when he finished 50th at the Open de France ALSTOM.[13] He had his best professional result in November 2009, when he finished 3rd in the Dunlop Phoenix Tournament in Japan.[14] In January 2010, Lowry finished in fourth place in the Abu Dhabi Golf Championship,[15] moving him into the top-100 of the Official World Golf Ranking.[16]
At the first FedEx Cup playoff event, Fowler finished T52 at The Barclays in the last week in August. The following week he again finished T52 at the Deutsche Bank Championship, the second FedEx Cup playoff event, after carding a disappointing six-over par final round 77. At that point Fowler was positioned 37 in the FedEx Cup points standings and required a strong performance at the BMW Championship to qualify in the top thirty for The Tour Championship; a performance which eluded him, finishing in 48th place. In finishing 43rd in the FedEx Cup, Fowler earned a $132,000 bonus.[21]
Nationwide Tour Players Cup: Playoff runner-up to Derek Lamely at the Nationwide Children's Hospital Invitational. Started the final round five shots behind 54-hole leader Dave Schultz. Held the lead during much of the final round but suffered a bogey at the 72nd hole of regulation to drop into a tie with Lamely and force a playoff. Lost to Lamely when he failed to get up and down from a greenside bunker on the second extra hole, missing his par putt of 12 feet. Lamely rolled in a three-foot par putt to win.
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.
Waste Management Phoenix Open: Won fifth PGA TOUR title at the Waste Management Phoenix Open in his 220th career start at the age of 30 years, 1 month, 21 days. Began the final round with a four-shot lead and won by two strokes after recording a double bogey and triple bogey en route to a closing 3-over 74. Became the first player since 1983 to win with both a double bogey and triple bogey or worse in the final round. Triple bogey came at No. 11 at TPC Scottsdale after he chipped his ball into the water and received an additional penalty when the ball rolled back into the water after he had placed it back into play. Marked the second time of seven occasions he converted a 54-hole lead to victory.
Hero World Challenge: After beginning the final round seven strokes out of the lead, closed with a tournament-record, personal-best 11-under 61 to win the Hero World Challenge by four strokes over Charley Hoffman. With a winning score of 18-under 270, won at the age of 28 years, 11 months and 20 days. His 61 topped the previous Hero World Challenge course record of 62, set by Albany resident Justin Rose during the final round in 2015. Prior to his 61, the previous low final-round score by a Hero World Challenge winner was 64, set on three occasions and most recently by Luke Donald in 2005. Opened his final round with seven birdies before making his first par on the par-4 eighth hole. No player has had as long a streak of birdies in an official PGA TOUR event to open a round since Joe Durant started round four of the 2005 Honda Classic with seven in a row. Added a birdie on the ninth hole to make the turn with an 8-under 28, turning a seven-stroke deficit into a two-stroke lead. His final round included 11 birdies, two more than his benchmark of nine birdies in official PGA TOUR events (final round of the Quicken Loans National in 2017). Finished the week at Albany Golf Club with 30 birdies, three more than his highest total in official PGA TOUR events (27 – 2017 Houston Open). Recorded his sixth top-six finish at the event in his sixth start (1/2017, T3/2016, 3/2015, T6/2014, T4/2012, T6/2011).
Lowry did not win on the European Tour from 2016 to 2018 but was joint runner-up in the 2017 DP World Tour Championship, Dubai and runner-up in the 2018 Andalucía Valderrama Masters. In January 2019 he won the Abu Dhabi HSBC Championship by a stroke from Richard Sterne. Lowry led by 3 strokes after three rounds but was two-over-par after 11 holes of his final round and dropped 4 shots behind Sterne. However he finished with 3 birdies in the final 7 holes, while Sterne had two bogeys, giving Lowry the victory.[20]

Immediately after the Masters in mid-April 2016, DeChambeau turned professional and signed a long-term agreement with Cobra-Puma Golf.[9] He made his pro debut days later at the RBC Heritage in South Carolina and tied for fourth, earning over $259,000.[10][11] 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,[12] and improved his world ranking to 148.
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.[19] Lowry made his Millwall debut three days later, where he played 90 minutes, in a 0–0 draw against Crystal Palace.[20] His impressive display at Millwall soon earned a loan extension.[21] 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.[22] 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."'[23]
Shell Houston Open: After opening with an 8-under 64 for a one-stroke lead on day one, added rounds of 71-67-70 to finish T3 at the Shell Houston Open. Erased a seven-shot deficit in the third round and started the final round three shots behind 54-hole leader Sung Kang, but a final-round 70 saw him finish four strokes behind winner Russell Henley. With 27 birdies on the week (tied for most with Henley), marked his most birdies in a single event.
Lowry missed the first three cuts of his professional career, but had his first payday on 5 July, when he finished 50th at the Open de France ALSTOM.[13] He had his best professional result in November 2009, when he finished 3rd in the Dunlop Phoenix Tournament in Japan.[14] In January 2010, Lowry finished in fourth place in the Abu Dhabi Golf Championship,[15] moving him into the top-100 of the Official World Golf Ranking.[16]
