Pratul Joshi stuns Hidayat; Saina concedes tie

India's Pratul Joshi created a flutter, shocking top seed and former Olympic champion Taufiq Hidayat in the first round of the men's singles in the Syed Modi International India Open Grand Prix Gold badminton in Lucknow on Wednesday.

The 18-year-old, a Delhi University student, displayed good touch to beat the Indonesian great 21-17, 21-12 in 30 minutes.

Joshi seemed as much surprised with the outcome as his opponent.

However, the joy of 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, Siswanto.

Overall, though, the boy from Dhar in 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.

The Hyderabadi girl also insisted that despite wanting to play she decided to pull out of this contest in view of the upcoming tournaments.

"I was not wearing my tape and was not at all confident with my knee injury which has prolonged since August 2012," said Saina.

India's K Srikanth also entered the pre-quarters with a comfortable win over compatriot Vinay Kumar Reddy, winning 21-12, 21-12.
