Waste Management Phoenix Open: Claimed his second runner-up finish at the Waste Management Phoenix Open, one shot behind Hunter Mahan. Had birdie opportunities on the last three holes but unable to catch Mahan. Previously lost in a playoff to Troy Matteson just down the road at Grayhawk GC in the 2009 Frys.com Open. Had he won at TPC Scottsdale, would have become the first Sponsor Exemption to do so since Jason Gore (2005 84 Lumber Classic). Lee Westwood later won in June as a Sponsor Exemption at the St. Jude Classic presented by Smith & Nephew.
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.
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.
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.
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).
World Golf Championships-HSBC Champions: Came to the 72nd hole in need of a birdie to get into a playoff with Tim Clark and Bubba Watson at the World Golf Championships-HSBC Champions. Hit a 5-wood from the fairway that came up short and went in the water on the par-5. Made par after taking a penalty and finished T3 after a final-round 70 at Sheshan International GC in Shanghai.
Lowry won for the first time as a professional in 2012, at the Portugal Masters in October. He shot a 67 to tie for the lead with the Englishman Ross Fisher, who made bogey on the final hole after missing a four-foot putt. The victory lifted Lowry back into the Official World Golf Ranking top 100 and made him eligible to compete in the WGC-HSBC Champions.
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. 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.
