The American, whose resume includes a major title at the 2009 Kraft Nabisco Championship, on Friday had a 36-hole total of nine-under-par 135.
She was in good shape to make a weekend run at a fifth tour title, and her first since the 2011 Canadian Women's Open.
American Lexi Thompson, the reigning Kraft Nabisco champion who shared the first-round lead with South Korea's Meena Lee, carded an even-par 72 and shared second place on 138 with defending champion and former world number one Park In-Bee.
South Korea's Park climbed up the leaderboard with a six-under 66.
New Zealand teen Lydia Ko, who could seize the world number one ranking from Stacy Lewis with a first major win this week, carded a 69 to head a group tied on 139.
She was joined by overnight co-leader Lee, who signed for a 73, and American Jane Park, who posted a 69 at Monroe Golf Club.
Half a dozen players were tied on 140. They included 2007 champion Suzann Pettersen of Norway, who shot 69, and 2012 winner Feng Shanshan of China, who signed for a 72.
They were joined by South Korea's Lee Mi-Rim (71), Paraguay's Julieta Granada (65), Spain's Beatriz Recari (70) and American Jennifer Johnson (70).
