Promising shuttler Arundhati Pantawane has finished runner-up in the Czech International Badminton Open tournament. The Indian's brilliant run in the event came to an end on Sunday after she went down in straight-games to fourth seed Kristina Gavnholt in the singles finals. Unseeded Pantawane lost 10-21 18-21 against the local player in 40 minutes. Pantawane had emerged a surprise runner-up at this year's National championships that was held at Rohtak.
