Olympic Silver medalist P.V. Sindhu defeated Carolina Marin in straight sets 21-19, 21-16 in 47 minutes at the India open Badminton Championship in New Delhi. Sindhu had lost to Caroline Marin in the Rio Olympics final and had to be content with silver medal. However the victory will be a huge booster for the Indian and soothe the pain of her Olympic defeat. Sindhu had also beaten Carolina in the Dubai World Super series Finals in December 2016.
