PV Sindhu had to settle for silver yet again at the BWF World Championships after losing the final in straight games against arch-rival Carolina Marin of Spain in Nanjing, China.Marin, who has been Sindhu’s toughest rival on the badminton court, prevailed once again over the Indian 21-19, 21-10 to clinch her third world title. The former world No. 1 shuttler had previously won the title in 2014 and 2015. She is now the first female player in history to hold three world titles.Sindhu couldn’t better her performance at the tournament from last year after failing to find rhythm and form in the final match against Marin, who took a 7-6 lead in the head-to-head battle against Sindhu.The star Indian shuttler seemed out of sorts throughout the match although, she did manage to put up a good fight for some time in the first game. Marin however, simply blew her opponent away in the second to win the match in just 45 minutes.(Match highlights)Marin proved too good for Sindhu in the match which mattered the most and brought out the full range of shots on court with surprising drop shots, constant varying of pace in a rally, down-the-line smashes and impeccable net play dominating her play.All through the tournament, Marin has looked in supreme form. Her confidence, her movement on court and her attacking strokes have been top notch.On the other hand, Sindhu had shown a lot more patience and variety in her strokes in this edition. Timely drop shots have been a major addition in Sindhu’s arsenal and that has helped her get past her opponents. Against Marin, she will need to bring all her variety to the court.advertisementEven though Marin and Sindhu have faced each other many times since the Rio Olympics final, this was the first major event after 2016 when they face each other in a final.Sindhu entered the final with a spirited performance against world No.2 Akane Yamaguchi of Japan and beat her 21-16, 24-22 to guarantee herself another silver medal.Marin on the other hand, played her semi-final against home favourite He Bingjiao and the Spanish player came from behind to beat the Chinese 13-21, 21-16, 21-13.
