Doha:�Indian tennis star Sania Mirza and Martina Hingis' 41-match winning streak came to halt after the world number one womne's doubles pair went down fighting in the quarterfinals of the Qatar Open, here. Sania and her Swiss partner Mirza lost 2-6 6-4 10-5 to Russian pair Elena Vesnina and Daria Kasatkina late last night. The last time the Indo-Swiss pair, who have won three doubles Grand Slams in a row, had lost was way back in Cincinatti last August. After surviving a gruelling three sets win over an unseeded Chinese pairing in the last round here, luck finally ran out for Sania and Hingis against the Russians despite dominanting the first set. Sania and Hingis have together won four titles this year out of an overall trophy count of 13. They started the year with wins in Brisbane and Sydney before completing a hat-trick of Grand Slam titles at the Australian Open. The duo had won the St Petersburg Ladies title earlier this month.
