On 27 January 2016, Lowry returned to Australia after a decade away from Australia when he signed a two-and-a-half-year deal with A-League side Perth Glory. Upon joining Perth Glory, Lowry said of the move, quoting: "I've got a lot of experience behind me now and I want to use it to guide the young lads who are in this young squad. I've spent 11 years in England and it's shaped my football over there and I'm really happy to be here and get stuck into the games"
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.
In July 2011, Fowler tied the 54-hole lead at the AT&T National, but an early double bogey on Sunday derailed his opportunity for his first PGA Tour win. Two weeks later Fowler finished tied for 5th in The Open Championship at Royal St George's. In August, Fowler finished in a tie for second at the WGC-Bridgestone Invitational behind winner Adam Scott, lifting him to 28 in the world rankings.
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.
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.
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).
