Korda made her birdie putt in the second group on the second playoff hole

``I was really calm,'' Korda said. ``I knew what the putt did because I'd had it before and it did not move. I was a little higher up and more to the right. I knew the line and I knew the speed. All I had to do was just hit it. It started breaking. I thought, `Oh, my goodness no, don't lip out, don't break too early.' I don't even know what side of the hole it hit. I was overwhelmed by everything.''

Making her 16th start as an LPGA discount golf clubs Tour member, Korda began the round with a one-stroke lead and was two ahead at 7 under after birdieing three of the first eight holes.

``I thought, `You've got to be kidding me,''' Korda said about the bogey run. ``I was lipping out and not reading my putts correctly. But I thought, `Come on, you can still get it back.' ... I was walking down the fairway like an absolute goof. After I made the birdie, I was OK, like, `I can do this.'''

Projected to jump from callaway diablo edge irons to 30th in the world ranking, she became the sixth youngest winner in LPGA Tour history and the fourth youngest to win a 72-hole event.

``All the times, I was down last year, it is all worth it,'' she said. ``It made me grow up. It made me realize that you've got to change your life to live out here and this is proof. I know that all the hard hours I put in and will keep putting in are really worth it. Every moment.''

Top-ranked Yani Tseng, the winner the last two years at Commonwealth Golf Club, was 1 under after a 74. The Taiwanese star had a three-hole stretch Friday in her second-round 76 Ping Anser Forged Irons when she dropped six strokes with a quadruple-bogey 8 and two bogeys. On Sunday, she had a triple bogey on the par-4 fourth, and bogeyed 15 and 16.

``If I didn't have the two bogeys late, I probably still would have had a chance,'' Tseng said. ``So it's good that I hung in there and fought back.''
