Ai Miyazato and Azahara Munoz both went well below par Thursday, and are tied for the lead after two rounds of the LPGA LOTTE Championship.

Munoz fired an eight-under 64 while Miyazato carded a 65 at Ko Olina Golf Club. They share first at eight-under-par 136.

In contrast to Wednesday's opening round, during which windy conditions kept scores low, Thursday's was full of red numbers. Jimin Kang shot a 66 to rise into a tie for third with Cristie Kerr (68) at minus-six, while Meena Lee's 65 helped her climb into a share of fifth at five-under 139. Suzann Pettersen (69) and Brittany Lang (70) also sit at minus-five.

However, not all players went below par Thursday, and some had big problems.

World No. 1 Yani Tseng stumbled to a few bogeys that limited her to shooting even-par 72, and remained at three-under. She is in a group tied for 12th.

Meanwhile, first-round leader Beth Bader struggled to a five-over 77 and fell into a tie for 41st, at plus-one. She still made the cut.

Michelle Wie, on the other hand, carded a four-over 76 that put her at plus-10. She posted a quadruple bogey at the first and missed the cut for the third consecutive event.
