He missed a birdie chance at the 16th which would have tied the lead, but the ball held up just short of the hole. An errant drive on the par four 17th left him with a tough approach and he clipped a tree leaving his ball well short of the green. He recovered well to land his third on the edge of the green but his par attempt finished short.
Needing an eagle on the par five 18th, Fox’s drive landed in the rough ending any hope of a playoff.
Fellow Kiwi Daniel Hillier finished in a share of 13th at 10-under following a final round 69.
A week after 23-year-old Ludvig Aberg produced a stunning finish to win the European Masters in Switzerland and help secure a spot on Europe’s Ryder Cup team, the 25-year-old Norrman produced a similar late flourish at The K Club to earn his second victory in two months — after the Barbasol Championship in mid-July — and underscore the talent emerging from Sweden.
Play was delayed for about 90 minutes because of bad weather soon after the leading groups teed off, with Rory McIlroy at that stage in a four-way share of the lead on 12-under par.
His bid for a second title at his home event, after 2016, tottered when he found water off wedge shots from the middle of the fairway at Nos. 7 and 11. By the time McIlroy went into the water twice at No. 16 in shooting triple-bogey 8, Norrman had already posted a target — 14 under — that none of his remaining title contenders could match.
“I think I was a little lucky — it was a long wait but I am super happy,” said Norrman, who turned pro in 2021 after attending Georgia Southwestern before moving to Florida State University.
“If you are winning, you are doing something good. It’s a world-class event and honestly I can’t believe this happened.”
Next week is the lucrative BMW Championship at Wentworth.
