PV Sindhu beat Denmark’s Amalie Schulz to book a clash with Akane Yamaguchi. (Badminton Photo) Lakshya Sen has not beaten Thailand’s World No 2 Kunlavut Vitidsarn in three years. Both times at the World Championships in 2023 and the French Open in 2024, his third sets were blowouts, pointing to lack in endurance. This year, he seems to be playing on a full tank, though when he runs into the local favourite on Friday, he will have only the slightest discomfort from his healing elbow – after he injured himself at the Thomas Cup.
