The 32-year-old Lowry shot 1-over-par 72 and claimed a six-stroke victory over Tommy Fleetwood of England as some of the best golfers in the world struggled in wind gusts up to 25 miles per hour on the Dunluce Links at Royal Portrush Golf Club https://www.royalportrushgolfclub.com in Portrush, Northern Ireland.
Smiling and with his hands thrust in his body-warmer pockets, Lowry junior walked up to the lofty 18th tee with a six-shot lead and the European Ryder Cup chant "ole, ole, ole" ringing all around him.
"It's like an out of body experience".
Asked how he had remained so calm under enormous pressure, Lowry replied: "I'll be really honest with you, I didn't!" I just love this place.
Lowry then birdied No. 15, while Fleetwood shot par, to push his lead back to six with three holes to go.More news: Chandrayaan-2: India set to re-attempt Moon mission launch
Three years after failing to convert a four-shot lead in the US Open at Oakmont, Lowry took the same advantage into the last day of the first Open staged outside Scotland or England since Max Faulkner triumphed at Portrush in 1951.
"I got off to a very shaky start", said Lowry, who had to sink a six-foot putt to salvage bogey at the first.
"Shinnecock - I felt great that week". "Today I was much more in the mix".
Shane Lowry's astonishing 63 on Saturday means that he headed in to Sunday at the top of the leaderboard by four shots, with Englishmаn Tommy Fleewtood joining him in the finаl pаir.
He needed to avoid any big numbers on his card and duly did so, making nothing worse than bogey.
He briefly wobbled when he made three bogeys in four holes on the front nine but his victory rarely looked in doubt. "I kept telling myself bogeys are not going to hurt you, let's just keep the ball in play and if I make the odd par it will be pretty good".More news: DirecTV NOW Loses CBS Sports Network
He was also hugged by Harrington and Portrush local Graeme McDowell, whose success as the 2010 US Open victor played its part in the Open returning to Northern Ireland for the first time in 68 years.
