The top four seeds in the 32-player girls main draw moved smoothly into the second round of the Tep Khunnah Memorial ITF Juniors at the National Training Center as the last of the Cambodian interest disappeared after Hour Sreypov and Ho Sreynoch lost their opening round singles matches.
While Sreynoch scrambled to get one game in the first set against Yun-Chen Hsieh of Chinese Taipei before being blanked out 6-0 in the second, Sreypov was beaten 2-6, 1-6 by another Chinese Taipei girl, Jou Cheng Chen.
The top-seeded Katie LaFrance of the United States led the parade of seeds, beating Pimrada Jatta-vapornvannit of Thailand 6-0, 6-1.
Second seed Risa fukutoku of Japan was equally efficient in her 6-1, 6-1 win over Jeovanne Canace Poernomo of Indonesia.
Continuing the one-sided trend, third-seeded Fang-Hsien Wu of Chinese Taipei was all over Sirinat Niyomsub of Thailand in a 6-1, 6-2 thrashing, while fourth seed Runa Ichinose of Japan was too good for Julia Daiya Barden of Singapore.
