Aucklands Liv Cheng has won for the first time on the Symetra Tour at the Gateway Classic at Longbow Golf Club this morning.

Cheng posted a two-under, 70 to come from two shots back heading into the final round to force the play-off which she won two holes later after her putter was running hot.

Cheng takes the first-place check of $15,000 and move to fourth on the Volvik Race for the Card money list after three events after starting the week in 72nd.

"It feels amazing and I still cant believe it," said Cheng. "Im over the moon excited."

Cheng made a 17-foot par putt on the 17th hole and a par on 18 to get into the clubhouse with the lead at 7-under. Mina Harigae (Monterey, California), who was the co-leader entering the day, made a 10-foot par putt on the 18th to force the play-off.

"I was out of position with my driver, but I stuck to it and scrambled," explained Cheng, who hit some tricky shots on the final two holes and in the play-off.

"I never gave up and trusted myself and the putts rolled in. I think I had 11 putts on the back nine and that really helped with scoring."

After two pars on the first play-off hole, Harigaes second shot went into the hazard on the second play-off hole and that opened the door for Cheng, who was able to drop an 8-footer for par to claim the victory.

"I feel like we kept going in the bunker together," said Cheng about the bunker shots both had to pull off in the play-off.

"I once again got out of position with my driver, but I scrambled to make the par which was great."

Cheng attempted just 24 putts for the day on her way to a very special victory.

"My putter feels really good right now, definitely the best club in my bag right now," said Cheng.

Cheng has had just one top 10 finish over her first two years on Tour. The win certainly puts her in a great spot early in the season.

"I feel really good about my game," said Cheng.

"This is my third year playing on the Symetra Tour and I feel like this year I have the tools in my game to play better and get myself on the LPGA Tour."

Cheng finished 63rd on the money list in 2016 and 108th as a rookie in 2015.

"The win this week makes me really happy that the hard work is starting to pay off," said Cheng. "Im definitely starting to see results."

Cheng was a four-time WCC First-Team performer while in college at Pepperdine.

"After college, I decided that I wanted to play professional golf and pursue a career," said Cheng.

"Ive seen some of my friends do well on the LPGA and that is where I want to be."

Cheng grew up playing junior golf with and against world No. 1 Lydia Ko.

She if the first player from New Zealand to win on the Symetra Tour since 2011 when Cathryn Bristow won. Bristow and Cheng are the only two from New Zealand to win in Tour history.
