Golf: Kiwi Ryan Fox rewriting wedding speech after European Tour victory.

Kiwi Ryan Fox has notched the biggest win of his golfing career, coming up trumps at the World Super 6 Perth - but it's ruined his wedding joke.

Fox thrashed Spaniard Adrian Otaegui in the matchplay decider on Sunday, winning the six-hole shootout with two holes to spare.

The win was Fox's first triumph on the European Tour, earning him a handy AU$258,330 (NZ$268,688) payday.

It's his first tournament win since 2016, when he won on the secondary Challenge Tour.

Fox is getting married next month and revealed his win in Perth has affected some of his plans.

"This win has actually killed one of my speech jokes," Fox said. "I was going to run my speech as a golf [victory] speech and say I haven't done one in a while.

"My mates were giving me a bit of stick about that, but they can't give me that anymore, which is quite nice.

"It's been 10 years in the making, getting married, and now I've got some practice kissing a trophy as well, which was nice."

Fox, whose dad Grant Fox was a World Cup-winning All Black, was forced to give up rugby after a series of concussions growing up.

The 32-year-old is currently ranked 85th in the world, but has his sights set on cracking the top 50. This result could see him rise as high as 64th in the world today, pending the outcome of the Genesis Open on the PGA Tour.

Fox becomes the first Kiwi to win on the European Tour since Danny Lee at the 2009 Johnnie Walker Classic. He narrowly missed a breakthrough win at the 2018 Irish Open, losing to Scot Russell Knox in the first hole of a playoff.

His next outing is likely to be the NZ Open in two weeks, where he will be a major drawcard

Australian Brett Rumford took out the inaugural World Super 6 in 2017, while Thailand's Kiradech Aphibarnrat won it last year.

But with the tournament's initial three-year contract now completed, there's no guarantees the event will be handed an extension.
