CANBERRA, Australia -- South Korea's Jiyai Shin won the Australian Women's Golf Open by two shots on Sunday, finishing with a 1-under 72 to break out of an overnight tie for the lead with teenage star Lydia Ko.
Shin mixed three birdies with two bogeys in a final round dogfight with Ko and world No. 1
Ko's share of the lead evaporated quickly on the final day with a double bogey, bogey start. However the 15-year-old amateur fought back to reclaim the joint lead after 13 holes before Shin calmly dismissed her challenge.

Shin effectively clinched her victory on the 14th hole when, tied with Ko at 16-under she holed an incredible pitch from deep rough to make birdie.
"I'm really surprised," Shin said. "There are so many good players here so I'm really happy to play well.
"I can't explain at the moment. I just feel excited."
Ko finished 3-over for the day and 14-under for the tournament, in outright third place.
Meanwhile, Tseng shot the best round of the last day -- a 7-under 66 -- to dash past Ko into outright second place, two shots behind Shin.
