Kung won 7-5, 4-6, 6-3 over Nao Hibino in the semifinals of Hua Hin on Saturday.
The 19-year-old qualifier from Switzerland, ranked No. 283, is coming from nowhere this week as she is into the first final of her career in only her second tournament. The wins have been good, too, as she has knocked out three seeded players. She'll be the underdog against No. 5 seed Magda Linette in the final.
