British teenager Mika Stojsavljevic was unable to back up her maiden WTA Tour win as she was knocked out in the last 16 of the Hong Kong Open.

Stojsavljevic, 17, shocked former Australian Open champion Sofia Kenin on Wednesday after being restored to the tournament as a lucky loser with only an hour's notice.

The Londoner was beaten 7-6 (7-5) 6-4 by Turkish world No 67 Zeynep Sonmez on Thursday in a little over two hours.

Stojsavljevic entered the Hong Kong Open ranked 411th in the world but is now just outside the top 350 in the live rankings following her victory over Kenin.

In 2024, she became the first Brit in 15 years to win the US Open girls' title, following Heather Watson's triumph back in 2009.

Stojsavljevic made her Billie Jean King Cup debut for Great Britain against Australia in Melbourne in April, defeating current world No 36 Talia Gibson in straight sets.

Sonmez's reward for defeating Stojsavljevic is a quarter-final against Katie Boulter's conqueror Claire Liu.

Three-time Grand Slam quarter-finalist, Sorana Cîrstea, is the top seed in Hong Kong, with Alexandra Eala the second seed.
