Jonathan Caldwell stormed to his first European Tour title with a brilliant final round of 64 at the Scandinavian Mixed in Gothenburg.
The Northern Irishman was three shots off the lead heading into Sunday, but responded in style to set a target of 17 under par.
After a blemish-free first 14 holes, including six birdies and an eagle, Caldwell bogeyed the 15th and 17th before responding with a gain on the par-four final hole.
Adrian Otaegui had a chance to snatch victory, but came unstuck on the 18th green for his only bogey of a final-round 67, leaving him a stroke behind.
Caldwell was free to celebrate a first title in only his 48th event on the European Tour, to which he returned via the qualifying school in 2019 after a decade away.
"It's been a dream of mine for an awful long time," said the 37-year-old. "A lot of hard work goes into it. It hasn't quite sunk in yet, but hopefully [there is] more to come.
"In 2009, I played my first year, lost my card, played mini tours and Challenge Tour over the years, worked as well in a local golf store. It's been a long road but finally, I'm here.
"The golf club at home will probably be going bonkers so just put a tab on and crack on boys and enjoy. My parents have been with me the whole way so I look forward to talking to them tonight."
At an event where 78 men and 78 women competed at the same course, Alice Hewson carded a final round of 69 to finish third, two shots ahead of Scott Hend and James Morrison.
Germany's Olivia Cowan closed with a 70 to finish in a share of 10th.
