World Number 6 Yani Tseng fired a blistering final round 7-under par 66 to win the 2010 Handa Women’s Australian Open at Commonwealth Golf Club by three strokes. The 21 year old from Taiwan, who had lurked among the leaders all week, birdied five of her final nine holes to hold off the challenge from defending champion Laura Davies. Last night I told my friends I was going to play really good today…I got a good feel on the greens. This is a really tough course and you just need to be patient. If you just lose a little focus, it is really bad. I tried to be focused and patient, Tseng said. For the last three holes my whole body was shaking. When I stepped up to putt I felt my heart going really fast. I told myself to be relaxed. I told my caddie to be relaxed too, she added. Tseng collected the $90,000 first prize ahead of Davies who closed with a 2-under par 71. World Number 8 and overnight leader Karrie Webb finished with a 1-over par 74 in outright third. I got off to a really great start. I was feeling pretty good out there until I played a couple of scrappy holes in six and seven and really lost a lot of momentum there. I just did not hit it as good after that, for some reason. I did not trust myself as much as I would have liked, Webb said. The Queenslander said a lack of trust in her putter hampered her progress. I did not feel as comfortable with the putter in my hand today. There was a bit more noise in my head than there has been. Italian Giulia Sergas finished tied for fourth place with Queensland s Katherine Hull who finished with a 1-under par 72. Australian Lindsey Wright closed with a 3-under par 70 to take sixth place. American Stacy Lewis finished one stroke ahead of leading amateur Hyun-Soo Kim from Korea at 1-under in eighth place. World Number 7 Anna Nordqvist finished at even par for the championship in ninth place.
