Shane Lowry stormed to a record 11-stroke victory at the Amgen Irish Open, the home crowd favourite shooting a seven-under 63 on Sunday to finish a staggering 23 under par.

It's Lowry's seventh career title and his second Irish Open triumph, following his 2009 victory as a 22-year-old amateur, with US President Donald Trump presenting him with the trophy.

The result was never in doubt at Trump International Golf Links in Doonbeg, however, as Lowry - holding a four-shot lead heading into Sunday - extended his advantage with a superb final round, while Trump watched on for the second consecutive day.

Lowry carded eight birdies for his round and just one bogey, at the ninth, with a pair of stunning 45-foot putts at the par-three seventh and par-four 15th sending the watching crowd into a frenzy. He capped his victory in style with another long-range birdie at the last.

Lowry had taken such a sizeable advantage into Sunday in large part thanks to breaking the course record with a second-round 62 on Friday. Jacob Skov Olesen, Lowry's closest challenger at 12 under and four shots back overnight, slipped down the leaderboard with a three-over 73. Patrick Reed's closing 64 and Rasmus Neergaard-Petersen's 63 were impressive enough to earn them second and third respectively, but Lowry had already surged clear. Joaquin Niemann took a share of second with Reed on 12 under, with Neergaard-Petersen one back.
