Oliver Lindell had piled the pressure on the Spaniard, carding a closing 69 capped by a birdie at the last to draw level at 10-under-par.

But Chacarra responded with a superb approach into the 18th, setting up a two-putt from around 20 feet to secure his second DP World Tour title, following last year's Hero Indian Open.

"Shot of my career, maybe!" he said of the approach.

"That was a little 'tweener' but with adrenaline I'm going to try to hit this one hard, it flew 10-15 longer than we thought. So, proud to see the ball land on the green and then took a nice first putt to give me a putt that you always dream of, a putt that you can't really miss to win a tournament."

The final round began with overnight leaders Sebastian Söderberg and Chacarra both dropping early shots, allowing Marcus Armitage and Maximilian Steinlechner to briefly share the lead after making two birdies apiece.

Momentum swung back Chacarra's way approaching the turn. Birdies at the eighth and ninth moved him to 11-under and three clear as Söderberg dropped two shots in three holes while Armitage and Steinlechner fell back with bogeys.

A bogey at the 12th after finding thick rough off the tee opened the door once more. Lindell closed the gap with a birdie at the 14th, while Söderberg slipped further behind.

Chacarra responded immediately, stuffing his approach at the 14th to set up a birdie and restore control.

Lindell and Steinlechner remained in contention after birdies at the 15th, with the Austrian knocking his approach to within a foot. Chacarra then bogeyed the 16th, but Steinlechner's challenge faded with a bogey at the demanding par-three 17th.

Lindell birdied the last to join Chacarra at the top of the leaderboard, forcing the Spaniard to produce one final shot under pressure.

He found the back of the green with his approach, lagged his first putt close and calmly tapped in for victory.

The winning moment sparked emotional celebrations.

"(I was thinking about) all the people that have been with me through my career.

"It's nice to win with my dad here. He's given everything for me since I was little so it was something very unique and I think of him, for sure."

After speaking on Saturday about his enjoyment of difficult conditions, Chacarra was tested throughout Sunday's windy final round. Only eight players broke 70, with Marcel Siem's 68 the low score of the day.

"Obviously it's something we can't control but the wind was there, it was changing and it was tough," Chacarra said.

"The pins were really tough, I thought, today, tough to hit it close after a good shot and there was always something close to them so like I said, we had a good gameplan, tried to be in the safe spot.

"The only one I didn't do very good was the 16th, I thinned it a little, I wanted to be five long and I mis-hit it and went to probably one of the worst spots, but I'm very proud of how I played the 17th and 18th holes, the hard work I've been doing, and it came through."

Lindell, who has now made all 16 cuts on the DP World Tour this season, finished runner-up after birdieing three of his final four holes.

Angel Ayora eagled the last to join Steinlechner, Söderberg and Joe Dean in a tie for third at eight-under. Julien Guerrier and Danny Willett were one shot further back, while Yanhan Zhou finished sixth-under and Sami Välimäki completed the top 10 at five-under.
