Seoul (AFP) - LPGA Tour rookie Angel Yin fired six birdies and one eagle to storm into the sole second-round lead at the LPGA KEB Hana Bank Championship on Friday (Oct 13).

The 19-year-old American fired a sizzling seven-under par 65 to post an 11-under total of 133, rising to the top of the leader board at the star-studded event that features the game's top-three players.

The highlight of the day came when Yin scored a par-five at the fifth where she hit a 6-iron to 12 feet and sank the eagle putt.

"That got everything started," Yin, who turned professional last year, said after the event at the SKY72 Golf & Resort in Incheon.

"I made a few pars in the beginning, but that eagle just fired everything up."

Local favourite Chun In Gee, a two-time winner on the LPGA tour, carded a 65 on Friday to a total of 135 to share second place with world No. 2 Park Sung Hyun and Ko Jin Young.

The current world No. 1 Ryu So Yeon scored a four-under par 68 to a total of 140 to lie 18th, while world No. 3 Lexi Thompson scored a 69 for a total of 138 to lie 13th in the table.
