An Se Young wins World Championship opener despite ankle injury

World No. 1 An Se Young began her BWF World Championships campaign in New Delhi with a straight-game win over Bulgaria's Kaloyana Nalbantova. The South Korean star scored 21-14, 21-13 but admitted her ankle injury is still healing and needs more recovery time.

After the match, An had her ankle iced and told reporters: 'It's a slow recovery.' The 23-year-old said she was happy to be back but acknowledged the challenge of the demanding tournament calendar. 'We should do our best and play our best. It's important not to get injured,' she said.

An, who won the India Open in January, said she likes playing in India. She is also working on her English, studying speaking three times a week. Her next match in the tournament is yet to be announced.
