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.
Lowry was the 2007 Irish Amateur Close Champion, defeating Niall Turner 4 & 3 in the final. While still an amateur in May 2009, he won The Irish Open on the European Tour, defeating Robert Rock on the third hole of a sudden death playoff. The win, on his tour début, made him just the third amateur to win on the European Tour, following Danny Lee earlier in the 2009 season, and Pablo Martín in 2007. Lowry shot a 62 to equal the lowest ever by an amateur on the circuit and led from the second round onwards.
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 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.
On August 26, 2018, he won The Northern Trust for his first playoff victory; in the process, he established a new record for the tournament when held at the Ridgewood Country Club, with a score of 266, besting the old Ridgewood record of 270, which was set in 2014 by Hunter Mahan. The following week, he won at the Dell Technologies Championship played at TPC Boston in Norton, Massachusetts, with a final score of −16, two shots clear of Justin Rose. This put him over 2000 points ahead of the second place player, Dustin Johnson, in the FedEx Cup rankings. This margin secured him top seeding at The Tour Championship, regardless of his finish at the BMW Championship. This also marked his fourth win on tour, third for the year, and second during the playoffs. At the Tour Championship, DeChambeau finished 19th out of 30 participants. As a result, he fell to 3rd in the FedEx Cup, winning $2,000,000.
Kolon Korea Open: Won his first tournament as a professional, the Kolon Korea Open on the OneAsia Tour, when he rolled to a six-stroke win over Rory McIlroy at Woo Jeong Hills CC in early October. He took control of the tournament in the third round when he shot an 8-under 63. He followed that with a 3-under 68 Sunday. The victory was worth a little under $250,000.
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.
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. He had his best professional result in November 2009, when he finished 3rd in the Dunlop Phoenix Tournament in Japan. In January 2010, Lowry finished in fourth place in the Abu Dhabi Golf Championship, moving him into the top-100 of the Official World Golf Ranking.
2019 Open Champion Shane Lowry, compared to Tommy Fleetwood, is on the other side of the spectrum in regards to brand loyalty. He is Cleveland/Srixon in 12 clubs including the ball with the only two exceptions being the TaylorMade M4 3-wood and his Odyssey Putter. In this case, that makes sense, those clubs seem to be a challenge to swap, especially the 3-wood, and Cleveland/Srixon isn’t really known for putters on the PGA Tour.
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.
“The switch was very easy. Even though he had won early in the year with another driver, he was not driving it good at all. He is very loyal to our team and our products that he came to us to find a new driver. He instantly loved the look of the Z 585 and once we started testing the numbers were exactly what he was looking for. His main comment about the driver is how his misses are minimal and he can hit all the shots he wants to.”
OHL Classic at Mayakoba: Birdied two of his last three holes at the OHL Classic at Mayakoba to fire a final-round 67 and finish in 2nd place, one shot back of Patton Kizzire. In his first start at the event, opened with a bogey-free, 6-under 65 to sit three back of Kizzire's lead. Followed with three-consecutives rounds of 67 in rounds two through four, resulting in a score of 18-under 266. Due to inclement weather Saturday, played his final two rounds on Sunday.
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.
