Lakshya Sen's dream run came to an end in the German Open final in Muelheim An Der Ruhr, Germany, on Sunday.Thailand’s rising star Kunlavut Vitidsarn stopped Lakshya's spectacular winning spree with a 21-18, 21-15 victory in the men’s singles final of the BWF World Tour Super 300 tournament.Much was expected from Lakshya Sen after his sensational victory over reigning Olympic champion and top seed Viktor Axelsen in the semifinals on Saturday.However, Lakshya could not repeat Saturday’s magical display as he crashed to a straight-game loss against Kunlavut Vitidsarn.World Championships bronze medalist Lakshya tried hard but could not halt the 21-year-old Thai’s spectacular run.In a battle between two unseeded players, world No. 20 Vitidsarn produced a scintillating exhibition of power and accuracy to shatter Lakshya's hopes.The 20-year-old Lakshya, who grabbed his maiden Super 500 title at the Indian Open in January, fought hard for nearly an hour but could not overcome a stiff challenge from Vitidsarn.Three-time world junior champion Vitidsarn, thus, recorded his fourth victory over world No. 12 Lakshya in their seventh meeting on the international circuit.
