Wuhan (China): India's Ajay Jayaram caused an upset, while P.V. Sindhu had an easy start, though Saina Nehwal, H.S. Prannoy and the doubles pairs exited the Badminton Asia Championships on the opening day here on Wednesday.

World No.13 Jayaram stunned Chinese fifth seed Tian Houwei 21-18, 18-21, 21-19 in an hour and 10 minutes to enter the second round where he will face Chinese Taipei's Hsu Jen-hao.

His fellow men's singles shuttler, Prannoy went down fighting to Hong Kong eighth seed NG Ka Long Angus in a 16-21, 21-13, 19-21 loss in an hour and a minute.

Rio Olympic silver medallist and fourth seed Sindhu defeated Dinar Dyah Ayustine of Indonesia 21-8, 21-18 in just 31 minutes in a relatively one-sided affair at the Wuhan Sports Center Gymnasium. Sindhu, the 2014 edition bronze medallist, will meet Japanese Aya Ohori in the next round.
