World number one An Se-young said she was “very proud” of her achievements after winning her 11th title of the year at the Korea Open on Sunday.

The 24-year-old defeated Japan’s Akane Yamaguchi 21-12, 15-21, 21-16 in the final in Yeosu to extend her unbeaten run, which dates back to March.

An has dominated the competition this year but said she remained cautious against world number two Yamaguchi.

“She’s a player who can always keep the score close, so I tried to maintain the intensity until the end,” An told the Badminton World Federation.

“When the match was over, I was very proud of myself. It felt a bit different because it’s my home tournament.”

The victory marked An’s 11th consecutive win over Yamaguchi, whose most recent victory against the world number one came in last year’s Korea Open final.

“Whenever we play each other, sometimes I win and sometimes she does, so I didn’t think too much about last year’s result,” An said.

“Yamaguchi is a player who brings different styles into every match, so I knew it wouldn’t be easy, and it wasn’t.”

An’s only setbacks this year came at the All England Open, where she finished runner-up, and the Japan Open, from which she withdrew due to injury.

She won her second world title in August in New Delhi and became the first woman to claim two Asian Games singles titles in Nagoya in September.

“We don’t play many matches in Korea, so this feels like a dream moment,” An said.

“I’m just so proud and happy that so many people in Korea are now supporting badminton.”
