Pak, Thompson share Kraft Nabisco lead
Lexi Thompson of the US plays a second shot at the par 5 ninth hole during the second round of the 2014 Kraft Nabisco Championship at Mission Hills Country Club on April 4, 2014 in Rancho Mirage, California - by David Cannon
Thompson's effort in perfect morning conditions on the Dinah Shore Tournament Course at Mission Hills gave her a seven-under par total of 137.
She was joined atop the leaderboard at the halfway stage of the first women's major of the year by Pak, who had two birdies in a two-under 70.
The two were one stroke in front of American Michelle Wie, who had two birdies and one bogey in her 71 for 138.
First-round leader Feng Shanshan of China was tied for the lead after a birdie at the par-four seventh, her 16th hole of the day.
But she closed with back-to-back bogeys for a one-over 73 that left her tied for fourth with Cristie Kerr on 139.
Feng, whose 2012 LPGA Championship victory made her the first Chinese golfer to claim a major title, finished with four bogeys and three birdies. Kerr carded a 70 to get to five-under.
Pak, winner of five major titles, is seeking her first Kraft Nabisco Championship win.
Thompson, 19, is seeking the first major victory of a career that saw her become what was then the youngest LPGA Tour winner in 2011 -- at the age of 16. She added two more titles to her resume since then.
