PV Sindhu won her first-round clash while Lakshya Sen crashed out of the men’s singles draw as India had a mixed day in the Kumamoto Japan Masters, a BWF World Tour Super 500 series badminton event, here on Wednesday. Two-time Olympic medallist Sindhu, who is hoping to make up for a disappointing season by winning the women’s singles title in this event, defeated eighth seed Busanan Ongbamrungphan of Thailand 21-12, 21-8 in 52 minutes.

Lakshya Sen, the Paris Olympic Games semi-finalist, ran into Malaysia’s Leong Jun Hao and crashed out in three games, losing 22-20, 17-21, 16-21 in a 74-minute battle of attrition. India’s top women’s doubles pair of Treesa Jolly and Gayatri Gopichand had lost in the first round on Tuesday.
