"I really wanted to win the championship and I refrained from thinking about it fearing that it would distract my attention, it was too hard. But I'm glad I've gotten it down," said the 20-year-old Beijing native who earned 120,000 yuan RMB ($18,779) for the win.

Liu Wenbo, the Chinese amateur who led through two rounds at Beijing Orient Pearl, closed with a 70 to finish equal third at two shots back, tied with compatriot Sui Xiang (68).

Chinese veteran Yang Taoli (69) was equal fifth at the 800,000 yuan RMB ($125,392) China LPGA Tour event, tied with Thailand's Wannasiri Sirisampant (70).

Keh, a 25-year-old from Pakuranga, posted her best finish on the CLPGA Tour on the strength of an outstanding round that featured eight birdies, including one at the last hole, and a lone bogey five at the 368-yard 11th.

"I'm pretty happy with my performance this week. It gives me more confidence. I am not really disappointed with the result today," said the second-year pro. "I played well and caught lots of chances. I am enjoying playing in China."

Nicollet Sharmila, the first round co-leader from India who was one shot back through 36 holes, ballooned to a 76 to finish equal 14th.
