"I don't think it's sunk in just yet," said the 27-year-old after finishing 16-under for the tournament.

"But I'm pretty sure when it hits home it's going to be a really happy moment for me.

"I think I've got a bad habit of making it hard for myself, but I'm happy I got over the line, as ugly as it was towards the end."

Lahiri, who soared into contention with a third round 62 on Saturday, got off to a fine start by birdieing four of his first five holes.

Lahiri said Saturday's round had been crucial to his becoming only the fourth Indian to win a European Tour title and was already calculating his chances of a Masters debut at Augusta National next year.

"In hindsight, that was one of the most crucial rounds of my career and it's fantastic when you play well at the right times," he added.

"The Masters is definitely one of my targets. I don't know how far I'll move up [in rankings], but I'm pretty confident now with this win I should have a pretty good chance."

Wiesberger's fourth successive top-10 finish put him in the top five on The Race to Dubai, but the 29-year old was left to rue his closing 74.

"It hasn't quite finished the way I intended to," said Wiesberger. "After the hiccup on five, I didn't hit it anywhere near as good as the last 15 rounds.

"It's tough to say, but it is what it is and, unfortunately, I beat myself out of it today."

Englishman Paul Waring (73) and Spaniard Alejandro Canizares (74) finished tied for third on 13 under, while defending champion Lee Westwood returned 75 for a share of fifth.
