Seoul: Two South Korean players were knocked out of the first round at the Women's Tennis Association (WTA) tournament taking place on their home soil Monday. Ku Yeon-woo lost to Lois Boisson of France in straight sets, 6-2, 6-1, in the round of 32 at the Korea Open at Olympic Park Tennis Center in Seoul.

According to Yonhap News Agency, Ku, 22, was also eliminated after her first match at her Korea Open debut in 2023 and then lost in the qualification round in 2024. Boisson, world No. 49, had a noteworthy run to the semifinals at this year's French Open, marking the first time a wild card has reached that stage since the Open era began in 1968. At 22 years and nine days old, Boisson became the youngest French semifinalist in a women's singles Grand Slam event since 1999. Boisson will next face No. 2 seed Ekaterina Alexandrova in the round of 16.

Earlier Monday, Park So-hyun lost to Katerina Siniakova of the Czech Republic by 6-2, 6-2. Siniakova is ranked 77th in singles but holds the No. 2 spot in doubles. She secured the women's doubles title at the Australian Open and the mixed doubles title at Wimbledon this year. Additionally, she is the 2021 Olympic champion in women's doubles and the 2024 Olympic gold medalist in mixed doubles. In the round of 16, Siniakova will meet Daria Kasatkina of Australia, world No. 16 and the 2024 Korea Open runner-up.

The losses by Ku and Park leave Back Da-yeon as the only South Korean left in the tournament. She will face the defending champion from Brazil, Beatriz Haddad Maia, in her first-round match Tuesday. The Korea Open is the lone WTA tournament played in South Korea each fall.
