HS Prannoy crushed All Britain finalist Shi Yuqi 21-17, 19-21, 21-17 in the primary round of the Swiss Open on Wednesday.
Prannoy had made the finals at Basel last year, going down to Jonatan Christie in the last.
In the last set, Prannoy drove 12-9, yet Yuqi returned into the lead before the Indian shut him to win 21-17.
Yuqi was searching for his most memorable title of the European swing in the wake of losing to Li Shifeng in Birmingham last week. It was a firm first round for Prannoy, who appears to have a preference for St Jakobshalle, and has performed well there.
The Indian fifth seed presently plays Christo Popov in the subsequent round. Kidambi Srikanth plays Lee Cheuk Yiu and Mithun Manjunath plays Chia Hao Lee in mens singles.
