KAPOLEI, Hawaii (AP) Su-Yeon Jang shot a 6-under 66 on Thursday at windy Ko Olina to top the leaderboard halfway through the second round of the LPGA Tour's Lotte Championship.

Jang, the 21-year-old South Korean player who got in the field on a sponsor exemption, is coming off a victory last week on the Korean LPGA. She had a 7-under 137 total in her second LPGA Tour start.

Defending champion Sei Young Kim was second after her second straight 69. The South Korean player won last month in Phoenix for her fourth LPGA Tour title in two seasons.

Third-ranked Lexi Thompson and Lizette Salas rallied, each following an opening 75 with a 66 to reach 3 under. Salas shot a tournament-record 62 three years ago before losing a playoff to Suzann Pettersen.

Top-ranked Lydia Ko, going for her third straight victory, was 1 under after a 72.
