Yani Tseng lead her disappear in the morning session and fought her way back into a place where she's been plenty comfortable this year.The top-ranked Tseng overcame a double bogey on her ninth hole to shoot a 2-under 70 on Friday for a one-stroke lead over Pat Hurst after the second round of the LPGA Championship, the tour's second major of the year.Hurst had a 67. Morgan Pressel, Minea Blomqvist, and Hee Young Park were 6 under after 69s.Battling a torrential downpour then a steady drizzle for nearly half her first nine holes, Tseng followed her first-round-best 66 with a gritty performance that put her at 8 under overall. She won the LPGA State Farm Classic two weeks ago for her second LPGA Tour victory of the year, and could become the first player since Lorena Ochoa in 2008 to follow a regular tournament victory with a win in a major.
