Joshi, a Delhi University student, was in belligerent form as he did not drop his speed at any stage and emerged victorious against the Indonesian 21-17 21-12 in 30 minutes in the USD 120,000 Gold Championship.
Joshi seemed as much surprised with the outcome as his rival.
However, Joshi's joy in the morning session proved short-lived in the post-lunch session as he lost the next round 18-21 21-16 20-22 to Hidayat's compatriot, the other Indonesian Siswanto.
Though, overall, the boy from Dhar (Madhya Pradesh) hogged the limelight on the opening day with his giant-killing efforts and gutsy display before crashing out.
"He (Taufiq) is my idol. I was completely blank during the match. However, I have been studying his videos on Youtube. I guess it helped me a bit today. At my age, he (Taufiq) was already playing in the finals of the All-England," said the self-effacing Joshi.
Hidayat seemed upset with the result and blamed "bad stomach" for his tardy show on the court today. "I had a bad stomach and I was not feeling well," said the top seed.

Apparently, Joshi was playing on painkillers due to a niggling bone injury, and it probably took a toll on him playing two high-pressure matches on the same day.
Meanwhile, London Olympics bronze-medallist Saina Nehwal conceded her first round match to Russia's Ksemia Polikarpova, citing injury and fatigue.
Saina, who had won the first game 21-17 and was leading 20-18 in the second, failed to continue further and gave a walk-over to her opponent.
Saina later said she had some problem in the knee, which increased during the match. (More)
