Just take it one shot at a time.

With those words from two-time champion Jane Crafter ringing in her head, Victorian teenager Su Oh stormed to an astonishing three-shot win in the Australian Ladies Masters on Sunday.

The 18-year-old, playing in her second tournament as a professional, reeled off four consecutive birdies on her last four holes to complete a four-under-par 69 final round and finish at seven-under for the event.

It was easily enough for the former amateur world No.1 to defeat 2009 champion Katherine Kirk and English pair Florentyna Parker and Charley Hull, who all finished in a tie for second at four-under.

Oh revealed she had sought out eight-times Masters winner Karrie Webb and Crafter in the lead-in to Sunday’s round for advice on how to take out professional events.

“I spoke to Jane this morning who won it the year I was born (1996). What she said really helped me on the golf course,” Oh said.

“She just said take one shot at a time. Karrie said `just don’t think, do it. Just let it go, keep doing what you’re doing’.”

Keeping a clear head couldn’t have been easy for Oh, who made three bogeys in her final three holes to blow a chance to win her debut professional event at the Victorian Open last week.

But the highly rated teenager, with her father S.G. playing a crucial role in keeping her calm as part of his caddie duties, showed a champion’s instinct that suggests she possesses a mental edge to go with her prodigious ability.

Kirk, a six-time ALPG Tour winner, said it was clear Oh has the ability to become whatever she wants.

“She looked pretty composed out there,” Kirk said.

“She’s obviously got the goods and we’re obviously going to see a lot of her in the future.”

Oh’s win not only earns her a $53,500 winner’s cheque, but a $50,000 bonus from tournament organisers, a two-year exemption on the Ladies European Tour and a spot at the Evian Masters and Ladies British Open.

If she can repeat her winning performance at next week’s Australian Open at Royal Melbourne, she’ll pick up a two-year exemption to the LPGA.

Having missed out on earning a card to the US Tour through Q-School last year, it would cap a dream start to life in the professional ranks for the talented teenager.

“It would be my dream two weeks but one win’s hard. Two wins? Yeah, maybe, we’ll see,” she said.
