PITTSFORD, N.Y. » Se Ri Pak, playing for the first time since injuring her left shoulder in early April, shot a 1-under 71 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.

Defending champion Yani Tseng followed her opening 76 with a 75 to finish at 7-over 151, making the cut on the number.

Slumping Michelle Wie missed the cut with rounds of 74 and 82. Hawaii’s Ayaka Kaneko (160) and Stephanie Kono (161) also missed the cut.

After Friday’s round, Grace Park, who won one major among her six victories on the LPGA Tour, announced her retirement. The 33-year-old Park made the cut at 6 over.

"I’m ready for a new phase in my life," said the oft-injured Park. "It’s my own fault for not taking care of my body."
