(CNN) -- In-Kyung Kim shot a sizzling seven-under par 65 to lead Michelle Wie by two shots at the halfway stage of the Dubai Ladies' Masters on Thursday.
The South Korean moved to nine-under after 36 holes in the Ladies European Tour event, in which she is playing on an invite, while American Wie carded 68 to follow up her opening 69.
Kim's compatriot Amy Yang was another shot back on six-under after shooting 70, level with Spain's Tania Elosegui, who holed in one at the par-three seventh in her round of 66.
First-round leader Maria Hjorth slipped to equal fifth place on five-under after a triple-bogey at the final hole, where the Swede twice hit the water hazard.
The 36-year-old had led by two strokes after an opening 66, but ended the second day level with British Open champion Catriona Matthew and Paraguay's Julieta Granada.
The 21-year-old Kim, ranked 10th with two wins on the U.S.-based LPGA Tour, benefited from having at her side caddy Terry McNamara, who carried the bags for Annika Sorenstam when the former world No. 1 won the tournament in 2006 and 2007.
"I think he has a little different yardage because Annika hits it further than I do. But he won here twice and he won the par-three event twice. I think I have the right caddie here," she told the tournament's official Web site.
Wie has been juggling her university studies during her trip to the Middle East, but was celebrating on Thursday after telling fans via her Twitter account that she had passed one.
