Yani Tseng will take a commanding lead into the final day of the Handa Ladies Australian Open after shooting a five-under 68 on Saturday. After getting off to a shaky start with an early bogey on the second at a rain-soaked Commonwealth Golf Club, the Taiwanese golfer fired six birdies for the remainder of her round to extend her overnight lead to three strokes ahead of South Korea&aposs Jiyai Shin. Tseng&aposs composure to fight back from an early setback outlined her star quality, with the 22-year-old recovering from a bogey on the second to immediately post a birdie on the next hole. The defending champion then continued to streak away from the field, with a hat-trick of birdies from holes six to eight creating considerable breathing space for the overnight leader. Tseng has fired just two bogeys in her first 54 holes at Commonwealth and it is hard to see her relinquishing her lead on Sunday. World number one Shin finished the day at 11 under overall for the tournament after shooting four under par on Saturday, with compatriot Eun-Hee Ji one shot further back at 10 under. Ji looked like she would slip out of contention for the title after shooting even par through 14 holes, but three consecutive birdies on the run home left her with a three-under round of 70. Local hope Katherine Hull was the big mover on day three, handling the wet conditions with aplomb to shoot a six-under 67 and surge into contention. The Women&aposs British Open runner-up in 2010 was three under after four holes and did not look back, finishing her round with seven birdies and a solitary bogey to leap to outright fourth on the leaderboard at eight under par. However, it will take a similarly impressive round on Sunday if she is to reel in runaway leader Tseng. Colombian MariajoUribe is one shot further back on seven under after carding a three under 70 on Saturday, but will be disappointed with a bogey on the 18th that soured an otherwise positive round. Australian Nikki Campbell slipped out of contention after she could only muster a one-under round of 72 to finish the day at six under. Campbell is now in a four-way tie for sixth alongside German Sanrda Gal and Americans Tiffany Joh and Cindy LaCrosse.
