Tseng won for a second straight week in Australia.
GOLD COAST, Australia (AP) -- Taiwan's Yani Tseng has taken over the No. 1 ranking in women's golf after shooting a final-round 68 to win the Australian Ladies Masters by four strokes.
Tseng, who won last week's Australian Open at Commonwealth Golf Club in Melbourne, finished Sunday's Masters at Royal Pines with a 24-under-par total of 264. Australian Nikki Campbell, with a final-round 64, and Stacey Lewis, who shot a 69, were tied for second.
Ryann O'Toole was fourth after a 69, six strokes behind Tseng.
Former No. 1-ranked Jiyai Shin of South Korea tied for second last week at the Australian Open. Shin did not play this week.
Seven-time Masters champion Karrie Webb shot a final-round 67 and was eight strokes behind Tseng.
Following up her seven-shot victory in defense of the Australian Open title last week, the 22-year-old Tseng's tournament total at Royal Pines was just two shots off Webb's tournament record of 262.
At one stage Tseng's lead was reduced to just two over Lewis and Campbell after a bogey on the seventh. But Tseng birdied the par-5 ninth and added another at the par-5 12th to all but put the tournament away.
