Olympic bronze medallist Saina Nehwal suffered a heart-breaking loss to Spain's Carolina Marin in the summit clash of the women's singles at the prestigious All England badminton championships in Birmingham today. The World No. 3 Indian finished as runner-up. She squandered an opening game lead to go down 21-16 14-21 7-21 to the reigning world champion in the final that lasted for little over an hour. Saina has been competing at the All England since 2007, and had never lost to Carolina. But the World No. 6 Spaniard scripted a remarkable comeback in the second game to put paid to the Indian's hopes at the Barclaycard Arena.
