SAN DIEGO: Jiyai Shin of South Korea shot a 3-under 69 to take a one-shot lead over No. 1-ranked Lorena Ochoa and Ai Miyazato in the second round of the Samsung World Championship at Torrey Pines on Friday.
Shin, who was tied for the lead after the opening round, has a 36-hole total of 135 atop the elite field of 20.
She was 10 under for the tournament after sinking a 20-foot birdie putt on the par-5 13th, but followed with a bogey and finished with four straight pars.
Ochoa, of Mexico, had a seesaw round of 69 that started with a bogey on No. 1 - her first of four - and ended with a 20-foot chip for eagle on 18. Her chip was from behind the hole, heading down toward the water.
Miyazato, of Japan, made a late charge and might have tied Shin, but her second shot on the par-5 18th splashed into the big pond that protects the green, leading to her only bogey of the day.
As she stood over her third shot, the fountain in the pond - known as Devlin's Billabong - suddenly turned on. It was quickly turned off.
She finished with a 68.
Miyazato had birdied 15 and 16 before her misadventure on 18.
Torrey Pines, the site of Tiger Woods' epic win in the 2008 U.S. Open, was shrouded in light fog but the golfers once again benefited from calm conditions.
Sweden's Sophie Gustafson shot a 70 and was fourth at 137.
There was a four-way tie for fifth at 138 among defending champion Paula Creamer (69), Cristie Kerr (66), Song-Hee Kim (72) and Na Yeon Choi (67).
