Michelle Wie won the second title of her career on Sunday, draining three straight birdies on the back nine to pace herself to a three-stroke victory at the CN Canadian Women's Open.

The 20-year-old American got a big ovation from the crowd in Winnipeg when she put in her final putt to finish the four-day tournament at 12-under par.

"I'm just so happy right now, nothing's really working in my brain," Wie told CBC Sports. "It was a fun day out there today and I'm just so happy."

The Hawaii native takes home the $337,500 US winner's prize.

She opened the day with a share of the lead along with South Korea's Jiya Shinn, but Shinn's round of 73 on Sunday was her worst of the tournament. Shinn finished in a four-way tie for second at nine-under.

Wie had three bogies — on 4, 12 and 17 — but kept her composure and added four birdies to finish at one-under par on the day.

"I was really nervous," said Wie, whose previous best finish this season was third place at the Tres Marias Championship in May. "I just went out there and tried to stay under par.

"You know it's just a confidence booster, and I'm just happy. And hopefully I can have a lot more [wins.]"

South Korean Jee Young Lee, defending champion Suzann Pettersen of Norway and American Kristy McPherson also finished at minus-9 and tied for second, earning $158,053 apiece in prize money. McPherson had her best round of the tournament, a six-under par 66.

Canadian Kane came close

Canadian Lori Kane had her best round, too, on Sunday, shooting a 67 to finish at five-under and in a tie for 11th. Kane, of Charlottetown, soared up the leaderboard after starting the day tied for 26th.

The 15-year veteran was a fan favourite at St. Charles.

"It always feels like I'm winning, especially when I'm home," a smiling Kane told CBC after her final round. "It's just really nice to have the support."

Kane was within three shots of the leader at one point Sunday, a far cry from Thursday when she had to sink a 25-foot put to make the cut.

"I put a good weekend together," she said. "I'm playing some really good golf. I'm playing golf that I remember I played when I won, when I first got out here."

She picks up $43,008 for her efforts.

Adrienne White of Red Deer, Alta., finished at five-over, shooting a final-round of 73, good for 1-over par on the day.

White finished one shot ahead of Montreal's Lisa Meldrum, who finished with a four-round score of six-over.

The tournament has a $2.25-million US purse.

No Canadian woman has won the event — the lone Canadian stop on the LPGA tour — since Jocelyne Bourassa in 1973.
