Kim going into the final round of the season-opening LPGA event and had the lowest score of the day with seven birdies and one bogey to complete at 15-under 273.Wie settled for a 70 to end second in the season-opening LPGA event, while Kim had a 71 and was another stroke back in a tie for third with Karrie Webb, who shot a 69. Paula Creamer was 5th at 8 under after a 71.Tseng captured the No. 1 ranking after winning back-to-back Ladies European Tour events, the Australian Open and then the Australian Ladies Masters last weekend. She previously won a small pro event in Taiwan."I just tried my best and I remember I had lots of confidence," Tseng said about winning three weeks in a row. "But with all the wonderful golfers out here, you never understand until the last putt drops in."Kim birdied three of her first 6 holes to sit tied for the lead with Tseng, and was at 13 under after a birdie on the 13th. However, she made a quintuple bogey on the 17th to fall out of contention, before finishing with a birdie to secure a tie for third.Wie also put pressure on Tseng by chipping in for a birdie on the first hole and obtaining 2 more shots on the sixth and seventh. But she didn't make another birdie the rest of the way and was four shots behind Tseng when she bogeyed the 17th."I feel like I played good out there today, yet on the back nine I just didn't make anything," Wie said. "Yani played great. She played like a rock star out there. She made every single putting and zero faults. Congratulations to her."Tseng may go for a fifth straight success next week in Singapore."I have lots of confidence and I'm longing for next week to see supposing that I would win," she said. "I feel very happy every week. I just focused on this week. I think to myself, 'Last week has passed, don't put pressure on this week.' Next week can be a new week and I'll enjoy it."
