India's youngest national champion Joshna Chinappa of Tamil Nadu set herself up for a coveted double when she entered the Under-19 women's final on the penultimate day of the Indian Oil Open squash tournament at the Otters Club in Mumbai on Friday.

Joshna, who is the top seed in both categories, blanked third seed Liana Deboo of Mumbai 9-0, 9-0, 9-0 and then got a walk-over in the women's final as her opponent Shweta Singh of Mumbai failed to turn up due to illness.

In the men's section, the top four seeds -- Saurav Ghosal of Tamil Nadu, Manish Chotrani of Mumbai, Gaurav Nandrajog of Delhi and Salil Vora of Mumbai -- kept their appointed places in the semi-finals scoring impressive victories.
