She is unwell but Indonesia's rising start Gregoria Mariska remains Indonesia's best bet in the women's singles in the World Junior Championships in Yogjakarta after she made the semi-finals.
The semi-finals assured Mariska, who is a victim of the flu bug, and Indonesia of the bronze medal but the colour of the medal could be different after earning a semi-final match against China's sixth seed and giant killer Cai Yanyan.
In the quarter-finals played at the Among Rogo Arena the Indonesian badminton darling notched a straight games 21-10, 21-13 win over compatriot and roommate Aurum Oktavia Winata in 27 minutes. Mariska is seeded fourth in the world championships.
Yanyan pulled off a stunning upset when she toppled top seed and favourite Pattarasuda Chaiwan in the quarter-finals with a 21-19, 14-21, 22-20 win to reach the last four.
Also through to the last four are Malaysia's 2015 junior world champion Goh Jin Wei, who is seeded fourth, and China's Asian Junior Under-19 champion Han Yue. Jin Wei defeated another Thai Chananchida Jucharoen 21-12, 21-5 while Han Yue outplayed compatriot Zhou Meng 21-13, 21-10.
Thailand, however, stayed on course for the men's singles title with top seed and recently crowned Asian Junior Under-17 champion Kunlavut Vitidsarn making the last four after a 25-23, 21-16 win over Japan's Takuma Obayashi.
Kunlavut will face China's Gao Zhengze in the semi-finals. The Chinese ended European hope Nguyen Nhat of Ireland with a 18-21, 21-18, 21-7 win in 56 minutes.
Malaysia's Asian Junior Under-19 champion Leong Jun Hao also kept his challenge alive when he downed French challenger Christo Popov in straight games 21-14, 21-12 and will face Japan's Kodai Naraoka for a place in the final. The Japanese upset second seed Lakshya Sen of India 14-21, 21-17, 21-14 in a 63-minute battled.
