INCHEON, South Korea (AP) -- Yani Tseng lived up to her top-ranked billing with a 7-under 65 on Friday to take the lead after the first round of the LPGA Hana Bank Championship.
The world No. 1 had ten birdies and three bogeys to take a one-stroke lead over Chella Choi, who capitalized on early mild conditions at Sky 72 Golf Club to set the early pace at 6 under.
Two-time defending champion Na Yeon Choi was in a tie for third place along with Sandra Gal of Germany at 5 under.
Paula Creamer and Sweden's Sophie Gustafson were part of a group of six players in a tie for fifth at 4 under, along with Koreans Meena Lee, Hee Young Park, Jimin Kang, and Mi Hyun Kim.
Michelle Wie shot 72 to leave her in a large group tied for 33rd place.
