Italian Marco Crespi claimed his maiden win on the Race to Dubai after claiming the NH Collection Open title with a two-stroke victory in Spain.
The 35-year-old two-time Challenge Tour winner, who finished the third round one shot off the lead, recorded five birdies and two bogeys to finish with a 69 on Sunday to claim a 10-under-par total for victory.
Crespi, who impressed with four birdies in the first nine holes, was delighted with his win and said: "I started very well today.
"I birdied the first and that gave me the confidence to go low and that's it. I just had to manage my pressure on the back nine."
Two shots off the lead were home challenger Jordi Garcia Pinto and Scotland's Richie Ramsay, who finished in a tie for second on eight under, while Chile's Felipe Aguilar and third-round leader Matthew Nixon of England were one stroke further back.
Nixon, who led following a superb 65 at La Reserva de Sotogrande on Saturday, suffered in the final round as he carded four bogeys, along with an eagle on the 15th and a birdie on the fourth, leaving him with 73.
Crespi admitted it was tough, with Aguilar coming close at one point before losing a couple of shots, but he was confident he could win it.
He added: "Felipe was very close, but he made a couple of mistakes so he made it easier for me.
"I lost a couple of shots on 12 and 13. On 12 I hit a very bad eight iron to the green, my only bad shot of the day. On 13 I had a very long iron, a three iron and it wasn't a really bad shot.
"But then I birdied the next. I really like the 14th because I birdied it every day.
"Anyway, I played very well and I am very happy."
Scotland's Marc Warren and England's Oliver Fisher did well to keep up the pace with the leaders, but eventually finished in a four-way tie for sixth after both carding a final-round 68 to finish on six-under-par, with Wales' Bradley Dredge a shot further back.
