Welcome to the coverage of Badminton World Championships final between PV Sindhu and Caroline Marin in Nanjing, on Sunday.

Olympic silver medallist Sindhu continued her incredible run of form at the World Championships, advancing to the final for the second successive year after seeing off Japan's Akane Yamaguchi in the women's singles semi-finals on Saturday.

Sindhu, who had lost to another Japanese Nozomi Okuhara in an epic title clash in the Glasgow edition last year after, notched up a superb 21-16, 24-22 win over World No. 2 Yamaguchi in a 55-minute hard-fought match.

Olympic champion and former two-time gold medallist Marin had robbed Sindhu off a gold medal at the Rio Olympics in 2016 after defeating the Indian in the summit clash.

Marin beat Chinese eighth seed He Bingjiao 13-21, 21-16, 21-13 to make her third World Championship final.

Sindhu has been in impressive form ever since winning the silver at the Rio Olympics in 2016. Last year, she won three titles out of the six finals that she reached.

However, loss in the finals in World Championship, Hong Kong Open and Dubai Super Series earned her the choker's tag.

This year too she has reached the summit clash at India Open, the Commonwealth Games and the Thailand Open but failed to cross the final hurdle, prompting many critics to once again describe her as the 'perennial bridesmaid'.
