Hyundai Tournament of Champions: Finished T6 in a Monday-start-Tuesday-finish event, the season-opening, 54-hole Hyundai Tournament of Champions. The event "started" twice during the regularly scheduled first round Friday and later Sunday, but both times PGA TOUR rules staff halted play due to unplayable windy conditions and subsequently voided all scores that had taken place. As the first player off the tee, he ended up hitting three "opening" shots of the season.
Presidents Cup: Closed out his second consecutive Presidents Cup appearance with a 6-and-4 victory over Emiliano Grillo, helping lead the United States to a 19-11 win over the International Team. Compiled a 3-0-1 overall record, highlighted by victories the first two days with teammate Justin Thomas in Foursomes (6 and 4 over Charl Schwartzel and Hideki Matsuyama) and Four-ball (3 and 2 over Branden Grace and Louis Oosthuizen).
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.
THE PLAYERS Championship: A week after collecting his first PGA TOUR victory, nearly became the first player since David Duval (1997) to post first two TOUR victories in back-to-back weeks, finishing T2 at THE PLAYERS, two strokes behind winner Matt Kuchar. Holed a birdie attempt from 21 feet, 7 inches on the par 3 17th in the final round to move to 11-under but couldn't convert a 7-foot, 7-inch birdie on No. 18 that would have given him the clubhouse lead at 12-under. Recorded his fifth career runner-up finish on TOUR in his 73rd start. His T2 performance came in his third start at THE PLAYERS and first in which he made the 36-hole cut. Moved into contention with a 66 in the third round, a career low at TPC Sawgrass. Entered the final round three shots off the 54-hole pace.
Enjoyed a stellar rookie season, with seven top-10 finishes and a 32nd-place finish in the FedExCup standings that led to him winning PGA TOUR Rookie of the Year honors. Finished inside the top 30 on the money list to qualify for the Masters and the U.S. Open. Played in first three Playoff events, slipping from 21st to 32nd and out of the TOUR Championship.
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.
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.”
On June 3, 2018, DeChambeau won the Memorial Tournament in Dublin, Ohio, in a sudden-death playoff against Kyle Stanley and An Byeong-hun, after the three finished regulation play tied at −15. After Stanley bogeyed the first hole of sudden death, DeChambeau then proceeded to win with a birdie on the second hole, giving him his second win on the tour.
World Golf Championships-Accenture Match Play Championship: In his fourth consecutive start at the World Golf Championships-Accenture Match Play Championship, fought his way to the semifinals Sunday morning against Ernie Els. Got off to a hot start, leading for seven of the first nine holes. With a shift of momentum, Els battled back and won three consecutive holes (Nos. 10-12) to gain a 2-up lead. Following an eagle and par on Nos. 13 and 14, he squared up the match. An Els birdie-3 at No. 18 sent the match to extra holes. A birdie-3 at the 19th hole (No. 1) gave him the upset win over Els.
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.
