PITTSFORD, N.Y. (AP) -- Se Ri Pak, playing for the first time since injuring her left shoulder in early April, shot a 1-under 71 on Friday to take a one-shot lead after the second round of the LPGA Championship.
Pak was at 3-under 141, one shot ahead of Inbee Park, Paula Creamer, Mika Miyazato, and Sandra Gal. Park shot a 70, Gal had a 71, and Creamer and Miyazato shot 72.
Defending champion Yani Tseng followed her opening 76 with a 75 to finish the two rounds at 7-over 151, and was positioned to barely make the cut in a tournament she dominated a year ago.
First-round leaders Beatriz Recari, Giulia Sergas and Ryann O'Toole, fell off the pace on a day that a swirling wind added yet another challenge on the narrow Locust Hill Country Club course. Sergas and O'Toole shot 76, and Recari had a 78.
Cristie Kerr, the runaway winner in 2010, was 2 under after a 76.
Slumping Michelle Wie missed the cut with rounds of 74 and 82.
