A relieved P.V. Sindhu let out a joyous scream when she finally laid her hands on a gold medal by claiming the World Tour Finals with a win over 2017 world champion Nozomi Okuhara here Sunday. With the straight-game victory, coming after seven straight finals losses, Sindhu became the first Indian to achieve the feat. Playing her third successive season-ending finale, Sindhu, who had lost in the summit clash to another Japanese, Akane Yamaguchi, to settle for a silver in the last edition, prevailed 21-19 21-17 in a match that lasted an hour and two minutes.
