Japan's Mika Miyazato shot a 4-under 68 on Saturday to take a two-stroke lead after the second round of the LPGA Tour's Safeway Classic.
Miyazato, tied for the first-round lead with Sydnee Michaels after a 65, had an 11-under 133 total on Pumpkin Ridge's Ghost Creek Course.
South Korea's So Yeon Ryu, the Toledo Classic winner last week, was second after a 68. Ryu and Miyazato, winless in her four seasons on the LPGA Tour, will be paired again Sunday after playing in the same group the first two days.
Cristie Kerr and Inbee Park shot 70 to reach 8 under, and Michaels had a 72 to join top-ranked Yani Tseng and Paula Creamer at 7 under. Tseng had a 67, and Creamer shot a 69.
Michelle Wie was tied for 11th at 5 under after a 70.
Defending champion Suzann Pettersen was 2-under after a 71. Last year, the Norwegian star Pettersen overcame a nine-stroke deficit in the final round and won in a playoff.
It was nearly 17 degrees cooler Saturday following Friday's scorching 38-degree day. Players said lower temperatures made the 6,611-yard course play longer.
