PV Sindhu on Sunday became the first Indian to win Badminton World Championships gold by beating familiar rival Nozomi Okuhara of Japan in a lop-sided final here on Sunday.

The Indian won 21-7 21-7 in the summit clash that lasted just 38 minutes.

Two years after being robbed off the gold by Okuhara in an epic 110-minute final at Glasgow that went down as one of the greatest battles in badminton history, Sindhu finally exorcised the ghost of that heart-wrenching loss with a completely dominating win over the same opponent.

It was Sindhu's fifth World Championships medal -- joint most for a woman singles player with former Olympics and world champion Zhang Ning of China -- to go with the two successive silvers and a couple of bronze medals.

Sindhu has also won an Olympic silver in 2016 Rio Games, a silver at Gold Coast Commonwealth Games, an Asian Games silver at Jakarta and the BWF World Tour Finals last year.
