CANBERRA, Australia -- Mariajo Uribe shot a 6-under 67 on Friday to overtake South Korea's Jiyai Shin and overnight leader Lydia Ko, claiming the second-round lead at the LPGA Tour's Women's Australian Open.
The Colombian opened with a birdie after teeing off on the par-4 10th and made four more at Royal Canberra, including at the sixth and seventh as she moved to 15-under 131 and a one-stroke lead.
Two-time British Open-winner Shin fired eight birdies against two bogeys for a 67, sharing second with 15-year-old amateur Ko, who followed an opening 63 with a 69 that included five birdies and a bogey on the par-4 14th.
Uribe, who turned pro in 2009, is chasing her first LPGA title and played a blemish-free round to follow her 64 Thursday.
South Korean-born, New Zealand-based Ko won the New Zealand Women's Open last Sunday for her third victory in a professional tournament. Last year, she won the New South Wales Open in Australia to become the youngest player to win a pro tour event and the Canadian Open to become the youngest LPGA Tour winner. She also won the U.S. Women's Amateur.
Shin took an early lead after the morning session, despite conceding bogeys on the par-4 9th and 5th holes.
"I hit it OK, but (it was) just the wrong read, so I still have a good feeling at the moment and with my good tempo, I'll just keep doing that for the next couple of days, too," Shin said.
Australia's Kristie Smith was fourth, five strokes off the lead after a 68, while Beatriz Recari was a shot further back after a 69.
