KUALA LUMPUR: K. Letshanaa is Malaysia's sole survivor in the singles events at the Korea Open after advancing to the last 16 in Yeosu today.

The world No. 28 avoided a third consecutive first-round exit by overcoming Thailand's Tonrug Saeheng 21-17, 21-18 in a 47-minute clash.

Letshanaa had crashed out in the opening round of both the Denmark Open and French Open last month.

However, she faces a tough test in the next round against South Korean world No. 1 An Se Young on Thursday.
