After three first round exits in the All England, Swiss Open and India Super Series, Srikanth finally got his form back as he notched up an upset 18-21 21-15 21-8 win over the world championship bronze medallist.
Srikanth, who was the finalist at the India Grand Prix Gold earlier this year, will next take on Hong Kong's Yun Hu in the quarterfinals tomorrow. The Indian has a 1-0 record against Hu, having beaten him at the Maybank Malaysia Open early in the season.
In the second game, Srikanth started troubling Tien and opened up a 8-5 lead after an initial battle. Tien soon clawed back with three points but the Indian managed to keep his rival at bay and slowly carved his way back into the contest.
Getting back his confidence, Srikanth was his dominating self in the decider as he didn't give Tien much opportunity and moved into the interval with a massive 11-3 lead.
