Scott Arnold has been threatening a breakout performance all year on Europe’s Challenge Tour and finally made good at this week’s Cordon Open with his first international win.

The talented Sydney-sider won by two shots after entering the final round one stroke behind leader Dean Huizing of the Netherlands.

After opening with rounds of 71-65-67 to put himself in position Arnold finished the tournament off in style, a 3-under-par back nine for a 2-under-par 68 enough to seal the win.

The 29-year-old has shown flashes of brilliance all year, including an electric final round 66 at The Open Championship in July, but has struggled to put together four good rounds.

Things looked to be getting away from Arnold again in the final round when he made the turn 1-over for the day and three behind playing partner Huizing but this time he rallied.

With three back nine birdies, including back to back efforts at the 15th and 16th holes, Arnold snatched the lead and held on for the win.

After raising the trophy Arnold told europeantour.com his perfromance at St Andrews had been a help in keeping calm under pressure this week.

"I think when I played The Open this year, it really helped me," he said.

"That was really good, I felt pretty comfortable out there. I was a little bit nervous today but it was more that I had to focus on what I was doing and hit some targets.

"I looked at the leaderboard for the first time on my way to the 16th green and I saw that I had a two shot lead, but I still had two holes to go so I was telling myself not to get carried away, because if you make one or two bad shots it can quickly turn into bogeys."

The former World Number One ranked amateur, Arnold is playing his second year on the Challenge Tour and is now a chance to graduate to the main Tour in 2016 via the Order of Merit.

The €32,000 winner’s cheque moves Arnold to 18th on the Order of Merit with the top-15 gaining promotion to the European Tour next year.

It would be Arnold’s second trip to the game’s second biggest stage after he earned a card through Q-School in 2013 but failed to keep it for last year.

Ryan Fox, who is having a breakout season of his own on the Challnge Tour, was next best of the Australasians in a share of 19th.

It was a disappointing finsih for the New Zealander after a brilliant third round 64 saw him enter the final round T5 and with a chance to claim his second title for the year.

However, he couldn’t recover from a poor front nine of 3-over-par and with two birdies and two bogies on the back fell down the leader board.

Rookie Geoff Drakeford was the only other Australian in the field but missed the cut with rounds of 74-75.
