Defending champion Yani Tseng shot a 6-under-par 67 to take a two-stroke lead in Friday's rain-interrupted second round of the Women's Australian Open at Commonwealth Golf Club.
Tseng had a two-round total of 9-under 137. South Korean Ji Eun-hee was two shots back after a 70 while top-ranked Jiyan Shin was also at 7 under when the storm forced her from the course after 15 holes.
Jennifer Song of the United States, who shared the first-round lead with Shin, shot 73 and was three shots behind Tseng.
The 58 players who did not complete their second rounds will begin play at 7:30 a.m. Saturday, with the 36-hole cut to be determined following the completion of the round.
Karrie Webb, who has won the tournament four times, was 2 under with one hole left to play in her second round.
Laura Davies shot a 76 and was tied for 43rd at 3 over, 12 shots behind Tseng.
Tseng, who moved up to No. 5 in the world rankings after winning two major titles in 2010, was out early on Friday and had six birdies and no bogeys as she continued to eye Shin's No.1 ranking.
''I was trying last year but I could not get there,'' Tseng said. ''This year I have a very good chance.
''She (Shin) is always on top and very consistent. I never expect she is going to miss any shot. That's how she is. She is a very good player and good for golf, too.''
