The NSW Open of 2012 will be remembered as the tournament where Lydia Ko wrote her name into the history books.

The 14-year old produced a bogey-free round of three under par 69 to run out a four shot victor to become the youngest winner of a professional golf tournament, man or women, in the history of golf.

Ko’s win made up for her heartbreaking loss last year at the same venue when she missed a short putt at the 18th and then lost to Swedish professional Caroline Hedwall.

“I got more nervous as the day went on, “ said the World Number One Amateur.

“When Lindsey got within two shots, I started to think back to last year with Caroline. Obviously, I am very happy to win, it means a lot to me.”

Ko broke Japanese star Ryo Ishikawa’s mark of winning at 15 years, 8 months, and Australian Amy Yang’s women’s record of 16 years, 192 days in the Australian Ladies Masters.

“It’s a pretty amazing feeling. I don’t know what to say. All I know is I played really consistent all week and I am really happy to be part of history. It’s like a miracle it’s not something you can have like clicking your fingers.”

Ko, who last week became the youngest winner of the Australian Amateur and only the fourth New Zealander in history to win the event, paid tribute to Guy Wilson who has coached her for the past eight years and also her caddy Steve Mowbray who she “enjoyed working with.”

She shared the moment with her Mum Tina who watched nervously at the Oatlands Golf Course.

“She was out there and giving me the thumbs up. It was great to have family here.”

Ko said she had little time to celebrate with the Australian Masters to prepare for but would enjoy a soft drink tonight and the chance to relax.

“It the most relaxing part of the day. I think I’ll go into a deep sleep tonight. I don’t think I’ll celebrate too much it is so meaningful inside but I have a tournament next week.”

Wales’ Becky Morgan finished in second place with a sensational final round of six-under par 66, while Lindsey Wright and Kristie Smith tie for third.

Ko began the final round with a four shot cushion over Wright, and it was Wright who got off to the best start with a birdie at the second to close the gap to three shots.

Both players went par-birdie over the next two holes before Wright gave back the shot she’d made up with a bogey at the par-3 5th hole.

Wright pulled with two shots with birdies at the 6th and 7th holes but that would be as close as she would get with the young New Zealander unflappable every time she was challenged.

Ko made the turn at 13-under, Wright at 11-under while Morgan and Smith were making up ground in the groups ahead.

The deciding hole seemed to be the 11th hole where Ko had overshot the green and had a very difficult up-and-down, while Wright had a difficult but makeable put from 10 feet.

Ko hit a good, but not great, chip and watched as Wright missed her putt.

The New Zealand Amateur then calmly rolled in her own par putt from 5 feet and it seemed that was the calming influence on her round.

Both players made pars on the next three holes but Ko put the first nail in the coffin when she made birdie at the 15th.

Wright could only make par and the lead was three. From there Ko’s Aussie pro rival fell away from with two more bogeys while Ko kept her blemish free round in tact with three pars to finish.

By the time she walked on to the 18th tee she held a four shot advantage and it was only the formalities left. She completed her round with a regulation par, but for the crowd it was not quite regulation.

Her tee shot on the short par-3 hit the flag and hole and ended off the left edge of the green. She two putted and it almost looked like she had amazed herself as she looked up at the crowd.

She said to dream of becoming the world’s best golfer was always her dream from the start.

“When I came to New Zealand I started golf and I knew if I tried hard that it would be possible.”

That dream looks another step closer as Ko’s win confirms her status as a truly world class talent and her performance at the Oatlands Golf Club in New South Wales has captured the imagination of the golfing world.
