Althea Gibson Club Court: Anna Kalinskaya staged an upset win over Australian Open champion Madison Keys to return to the quarterfinals in Charleston for the first time since 2023.
Kalinskaya was a 6-2, 6-4 winner against No. 2 seed Keys, taking advantage of an erratic performance by the World No. 5 to score her first Top 10 victory in 10 months and advance to her second quarterfinals of the season.
Kalinskaya, who peaked at a career-high ranking of No. 11 last October on the back of a 2024 season that saw her reach a WTA 1000 final in Dubai, a WTA 500 final in Berlin, and the second week of two Grand Slam events, entered Charleston at 4-7 on the season and having won back-to-back matches at just one tournament, in Singapore in February (where she retired in the semifinals), reports WTA.
