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.
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 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.
The form and fitness of centre-backs Michael Morrison and Jonathan Spector and left-back Jonathan Grounds restricted Lowry to a seat on the bench until mid-December. He eventually made his debut in the starting eleven for the home fixture against Cardiff City on 18 December, standing in for the injured Grounds at left back. He appeared once more, in the FA Cup, before his contract was cancelled by mutual consent to enable him to return to Australia.
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.
Frys.com Open: At the Frys.com Open in Scottsdale, Ariz., reached a three-way playoff with Jamie Lovemark and eventual-winner Troy Matteson. Began the final round four strokes behind Matteson, but played his first five holes in 5-under, punctuated by a hole-in-one from 211 yards at the par-3 fifth hole. After finishing T2 in the playoff, he had recorded all eight of his professional rounds in the 60s. Thanks to the T7 in Las Vegas at the Justin Timberlake Shriners Hospitals for Children Open and T2 finish at Grayhawk GC, he surpassed No. 150 from the 2008 money list, earning special temporary membership on TOUR for the remainder of the season.
The Barclays: Held a one-stroke lead over Patrick Reed after 54 holes at The Barclays in the FedExCup Playoffs, before a double bogey-birdie-bogey finish on Nos. 16-18 resulted in a T7 at 6-under 278 with Jason Kokrak and Ryan Moore. Fowler went bogey free at Bethpage Black from the 10th hole in round one until the 11th hole in the final round, a span of 55 holes. His 55-consecutive holes without a bogey became a personal best on the PGA TOUR, besting 53 from the 2010 Memorial Tournament. This streak also marked the longest recorded in Barclays history since hole information began in 1983. Ian Poulter had the longest with 45 in 2010. The finish marked his third top-10 showing in his last four starts in the event (T9/2013, T9/2014).
