( CNN ) -- South Korean golfer In-Kyung Kim retained the lead at the halfway stage of the season-opening LPGA Thailand event on Friday , but is being chased by world No . 1 Yani Tseng and Michelle Wie . The 22-year-old Kim , seeking her fourth victory in successive years on the top women 's circuit , faltered with a one-over-par 73 at Siam Country Club 's Old Course but ended the day with a one-shot advantage . Kim , who finished third in two of last season 's four majors , had matched the course record of 63 in her opening round on Thursday . Taiwan 's Tseng carded a 71 in soggy fairway conditions following heavy rain earlier this week , while American Wie joined her on seven-under 137 after a 68 . `` I feel exhausted . It 's the first event , but it feels like the last event , '' Kim , who had four bogeys in her opening nine holes , told reporters . `` It was such a difference coming from yesterday when I teed off first and I did n't really expect much . I do n't know , I think I was too hard on myself the first nine holes and I could n't really find a rhythm . '' Wie said the greens were drying out in the hot sun . `` I think it 's a lot firmer . The greens are very fast . I need to stop hitting it five feet past the holes on my putts , '' she said . Americans Paula Creamer and Juli Inkster were tied for fourth on five under , shooting 70 and 73 respectively to be level with Japan 's Momoko Ueda ( 69 ) and South Korea 's Na Yeon Choi ( 70 ) . Norway 's Suzann Pettersen , who won her first major title last year , was tied for eighth after a 72 . Defending champion Ai Miyazato was tied for 25th after a second-round 69 . Meanwhile , Spain 's Rafael Cabrera-Bello holds a one-shot lead after the fog-delayed second round of the men 's European Tour event in India . The world No . 125 shot a three-under 69 at the Avantha Masters in New Delhi on Friday to be clear of a bunch of six players at the halfway stage . Of that group , Thailand 's Thongchai Jaidee and Indian Jeev Milkha Singh can both pass his total of eight-under 136 when they complete their final seven holes on Saturday . World No . 68 Jaidee is the only player in the field ranked inside the top-100 . An incredible nine players shared the lead after the opening round of the PGA Tour 's Northern Trust Open in Los Angeles on Thursday .
