Elvina Kalieva, the 23-year-old American ranked around No. 115, enters this US Open qualifying match after straight-set wins over Kristina Mladenovic and Sofia Costoulas on hard courts, building on a solid 2026 campaign that included a Memphis semifinal. Vendula Valdmannova, the 18-year-old Czech at approximately No. 165, arrives on a hot streak with nine wins in her last ten matches, highlighted by recent victories over Maria Lourdes Carle and Aliaksandra Sasnovich plus strong ITF and Challenger results on hard courts. Kalieva brings greater main-tour experience and home-crowd support in New York, while Valdmannova’s youth, recent momentum, and aggressive form create a competitive matchup with realistic upset potential on the hard surface.
