Hall of Famer Pak Se-ri of South Korea shrugged off the effects of a shoulder injury and pushed past a quartet of rivals to seize a one-stroke lead after 36-holes at the LPGA Championship here Friday. The 34-year-old Pak, winner of five major LPGA titles, shot a one-under-par 71 for a three-under-par 141 total on a windy day at a Locust Hill Country Club course lined with deep, unforgiving rough for the second women's major of the year. Tied one stroke behind Pak on 142 were 2010 US Open champion Paula Creamer, who shot level par 72, 2008 US Open winner Park In-bee of South Korea (70), 2010 Japan Women's Open winner Mika Miyazato (72) and Sandra Gal of Germany (71). Six players were bunched another shot back at one-under-par 143, including former champion Suzann Pettersen of Norway. World No. 1 Tseng, who won the title last year by 10 strokes with a 19-under-par total, made the cut.
