Brooks Koepka's Open challenge faded at Royal Portrush but the American still became just the fifth man to secure a top-five finish at every major in a single season.

After finishing tied for second at the Masters, winning the US PGA Championship and claiming second outright at the U.S. Open, Koepka had to settle for a share of fourth on six under par in Northern Ireland, nine shots adrift of runaway winner Shane Lowry.

A closing 74 spoiled his weekend, after rounds of 68, 69 and 67 put the 29-year-old in the hunt for the Claret Jug.

Before Koepka's feat, Jordan Spieth was the last man to achieve the full house of top-five finishes when he won the Masters and U.S. Open in 2015 as well as enjoying strong runs at the Open and US PGA.

Rickie Fowler, still yet to win a major, was a model of consistency in 2014, with two second places, a third and a fifth.

Tiger Woods had three major wins in his 2000 season, plus a fifth place at the Masters, and in 2005 he triumphed at the Masters and Open Championship, while coming second at the U.S. Open and tying for fourth at the US PGA.

Jack Nicklaus won the US PGA in 1971 and 1973, and in both seasons also bagged top-five finishes at the other majors.

Despite joining such an elite club, Koepka was not impressed with his efforts at Portrush.

"I don't see much positive out of it," he said after his final round. "If you don't play good you're not going to win. So it's very simple. It's disappointing, yes. I didn't play the way I wanted to. And I've got to live with that."
