The Chiang Mai player beat compatriot Sappanyu Avihingsanon 21-15 21-19 to win the Yonex Sunrise Vietnam Open in Vietnam, by far the biggest victory of the 23-year-old’s career and very timely after he lost the Games final to Indonesia’s Jonatan Christie a fortnight ago.
“I felt all the hard work finally paid off. Winning here is beyond my expectations as I came here a bit tired from the SEA Games,” said the world No 40.
“But I tried to hang in there and fight. I tried to take charge at the net and move him around. I played well when I needed to.”
Khosit will take a week off before joining the Japan Open Super Series, where he reached the quarter-finals last year.
“Unlike in Vietnam, I will be an underdog against anyone in Japan as there are many top players. I hope to continue with this form,” said Khosit, who is now aiming to crack the top 30 by the end of the season.
In the women’s doubles third time was lucky for Chayanit Chaladchalam and Phataimas Muenwong as they finally captured a title for the first time after losing two finals this year, the Thailand Open and World University Games.
They beat Della Destiara Haris and Rizki Amelia Pradaipta of Indonesia 21-16 21-19 for their maiden World Grand Prix victory.
“We are playing better and better over the past few months. It’s a pay-off from training seven days a week to fix mistakes that we used to make in the past,” said Chayanit from Nakhon Si Thammarat.
Phataimas, from Surat Thani, said: “After losing two finals, we were confident we would win as we were well prepared and learned from those two losses. Now it’s time to celebrate.”
