Mika Stojsavljevic vs Marta Kostyuk Prediction & Picks - WTA London - Queen's

Prediction published on 6/9/26, 4:54 AM  by Lou Aguila in Tennis Picks

Hot off her first Grand Slam semifinal at the French Open, Marta Kostyuk shifts her focus to the grass courts.

The Ukrainian opened as a heavy favorite (-900) over Britain’s Mika Stojsavljevic (+580) in the first round of the 2026 HSBC Championships.

Kostyuk had racked up 16 consecutive victories before the streak ended in a semifinal loss to Mirra Andreeva 1-6, 3-6 at the French Open. Despite falling short of a Grand Slam title, Kostyuk achieved a new career high in the world rankings at No.12. The grass-court season will serve as a litmus test for Kostyuk if she can sustain a high level of tennis on a whole new surface.

The 261st-ranked Stojsavljevic received a wild-card entry into this WTA 500 event. The Brit reached the quarterfinals of the 2026 Birmingham Classic, falling to eventual runner-up Nikola Batunkova in three sets 4-6, 7-6, 6-7. Stojsavljevic owns a 3-8 record on grass.

Difference-Maker: Despite Kostyuk’s subpar win rate on grass, the Ukrainian remains a hot pick in the moneyline and spread market as the majority of the bettors believe she can sustain her upward trajectory. Also, the 17-year-old Stojsavljevic hasn’t faced a player of Kostyuk’s caliber.
