Romero, who was without playing status on any Tour, surged to the top of the leaderboard with a bogey-free closing 65 to reach 17 under at Golfclub München Eichenried in Germany. His seven birdies included five in the last eight holes.

Having set the clubhouse mark, Romero had to nervously wait as Masters Tournament champion Sergio Garcia, England’s Richard Bland and Belgian Thomas Detry tried to better him.

Romero, who had earlier birdied the final hole, finished a stroke clear of the trio with the final pairing of Bland and Garcia both carding costly late bogies leaving the Argentinian in front. It was his first European Tour title since the Deutsche Bank Players' Championship of Europe in 2007. It was his first professional win since the 2014 Carlos Franco Invitational on the local Argentine Tour.

"I'm really happy, after ten years winning on the European Tour, especially here in Germany. I'm really, really happy," the 36-year-old said.

"The whole round was very good. I was focused all day. I didn't make any bogies, that is a rare thing for my type of game. The last few holes I noticed I made seven birdies but the whole round was excellent.

"I was nervous when I got to the 18th green but finally when I was thinking with two putts I could win the tournament, I was really nervous. But hopefully I was going to do a two-putt and now I have my trophy and enjoy this moment."

FINAL SCORES

Detry closed with a 66 to finish at 16 under alongside Garcia and Bland, who both carded rounds of 69.

Brett Rumford was the best of the Australians, finishing T34 after a disappointing 75 in the final round. The West Australian had played his way into contention and was just five strokes from the lead after 54 holes. But a bogey at the opening hole of the final day set the tone the remainder of the round.

South Australia’s Wade Ormsby, who led the championship after 18 holes with a first day eight under 64, was a stroke further back at four under and T44.
