Jon Rahm celebrates a maiden victory on home soil as a professional with a three-shot win at the Open de Espana.
He was hunting a first national title as a professional to add to his two previous European Tour wins in Dublin and Dubai a year ago.
Moments later, Rahm birdied the last to secure a third win from only 19 European Tour events, making him the third-fastest player to reach that mark.
"It's hard to describe the feeling of satisfaction and pride I have right now", Rahm said. "It's truly been the hardest Sunday I've ever had in any tournament that I've won because the crowd wanted it so much and I wanted it so much".
"You can tell how excited everybody is, I felt that tension, I felt that stress, I felt everything magnified".
"I'm just happy to play the way I did and to get it done", Rahm said after his victory.
"I've been blessed to be national champion with the Spanish Golf Federation many times, European champion and world champion representing them. So being able to win this as a pro and do this for them and the Spanish people feels great".
While Elvira eagled the par-five fifth to snatch the solo lead, it came between bogeys at the fourth and sixth and he would undo back nine birdies at the 13th and 14th with that double bogey at the 17th.
Rahm played a handsome chip at the first to set up a birdie and when he hit a huge drive on the second to set up another gain, he was in a share of the lead with Dunne. Rahm, who had birdied three of the opening seven holes, bogeyed the ninth to open up a three-way tie at the top of the leaderboard.
Jason Scrivener finished at the tail of the field after a second over par round of the weekend, his 1-over 73 dropping him to minus one for the 72 holes.
Spain's Nacho Elvira had seemed well placed to challenge Rahm, but he sent his tee shot on the short 17th into the water and paid the price with a double bogey.
Dunne also birdied the last to take second place on his own.
The Spaniard, who's now the World number four, claimed a two-shot victory after carding a closing 67 to move 20 under for the tournament.
Frenchman Julien Guerrier, South African Jacques Kruyswijk and Japan's Hideto Tanihara finished six shots off the lead.
