The 19-year-old progressed through the preliminary rounds at the Singapore Indoor Stadium and will play in the main draw of a Badminton World Federation (BWF) Super Series event for the first time.

She comes from a badminton family as she is the daughter of Japan coach Riony Mainaky and niece of Olympic gold medallist Rexy Mainaky, who won the men's doubles title for Indonesia with Ricky Subagja at Atlanta 1996.

The teenager first saw off Chinese Taipei's Chen Hsiao Huan 26-24, 14-21, 21-19 before knocking out Singapore's home hope Ai Ninna Tan, 21-7 24-22.

Her prize is a first round clash against Canada's Commonwealth Games champion Michelle Li.

“She is very happy and excited," said Rexy Mainaky, who was watching from the stands and is now the technical director of the Indonesia Badminton Association.

"She has been going to tournaments for two to three years now and it’s the first time she has gotten this far."

Another Indonesian woman, Yulia Yosephin Susanto, is also through after a shock second round preliminary win over the qualifying second seed.

She beat Swiss player Sabrina Jaquet 22-20, 24-22 after beating Singapore's Quek Chun Yi 21-9 21-11 in round one.

Her reward is a clash with Japan's overall second seed Nozomi Okuhara in the first round.

In the men's draw, the talking point came when Malaysia's Zulfadli Zulkiffli knocked out his younger brother Zulhelmi Zulkiffli 21-14, 21-11 in the second round.

Sony Dwi Kuncoro of Indonesia and Japan’s Kenta Nishimoto also came through qualifying, but Singapore's Derek Wong fell at the second hurdle to Chinese Taipei’s Lin Yu Hsien, 21-14, 21-16.

The main draw will begin tomorrow.
