MIRABEL, Quebec (AP) - Brittany Lincicome was singing in the rain Sunday in the Canadian Women's Open

"I was very patient, singing a lot of songs, very chatty," Lincicome said after her second LPGA Tour victory of the season and fifth overall.

"The weather was not great, but I was still having fun. I'm definitely going to remember this win."

To stay focused, the long-hitting American sings to herself as part of her sports psychology program.

She wasn't quite ready for an encore in the media center.

"I'm not a good singer, so I'm not singing for you," she said.

Lincicome, with former Canadian player A.J. Eathorne working as her caddie, saved par on the 18th hole for a 2-under 70 to edge defending champion Michelle Wie and Stacy Lewis by a stroke at Hillsdale Golf & Country Club. Lincicome finished at 13 under and earned $337,500.

"I never won on tour myself, so it's kind of cool to say I've been involved in two wins in one year," Eathorne said. "I guess, I never thought it would get that good, that fast.

"It's been a lot of fun this week being a Canadian in Canada. Everyone's asking me why I'm not playing and obviously there's a very good reason I'm not playing. I've got a great job. I can be involved in a win and I know my game is not where it needs to be to do that."

Lewis shot a 67 - the best round of the day - to match Wie (72) at 12 under.

"I knew the day was going to be hard and you just have to get through it - grind over every putt and every shot," said Lewis, who got in 15 holes before the rain started.

Wie, the winner last year at St. Charles in Winnipeg, Manitoba, needed a birdie on the 18th to force a playoff, but missed the green, took a drop to get clear of a fence, and made par.

"I'm proud of the way I hung in there," Wie said. "Coming in, I had a lot of clutch shots that I can really take positives from. It feels good to be back in contention again."

U.S. Solheim Cup players took the top five spots, with Cristie Kerr (71) and Angela Stanford (72) tying for fourth at 11 under.

Fears that the fourth round wouldn't be concluded because of remnants of Tropical Storm Irene didn't pan out. It rained heavily on the back nine for the leaders and the wind gusted, but play was never stopped.

Organizers moved up start times by 90 minutes, grouped the players into threesomes instead of twosomes, and sent them off both the first and 10th tees to get the round in before the course could be washed out.

If the final round had been wiped out, there would have been a playoff among 54-hole leaders Wie, Tiffany Joh and Ai Miyazato. Joh shot a 76 to tie for 12th at 8 under, and Miyazato had a 77 to tie for 16th at 7 under.

Lincicome pulled her tee shot on 18 into a tent and had to take a drop, but managed to get the ball up near the green, chip it close and make the winning putt. She also had fine saves on the eighth and ninth.

"I'm growing as a golfer, I guess," said Lincicome, also the ShopRite Classic winner in early June outside Atlantic City, N.J. "If this would have happened a couple of years ago, I'm not sure how I would have handled it."
