An American gem that keeps on delighting!

Anna Kalinskaya, 23 years old, Russia, world no. 22, right-handed. The Russian is a regular at this stage in Charleston, with two quarterfinals in two appearances, and she comes into this match off a clean, commanding win over Badosa yesterday, 6-4 6-2. Her 2026 season is solid at 11–7 and she has shown this week great control on Har-Tru. Her serve holds up well on this surface, with 73% of service games won on clay over the last 52 weeks, and she converts her break points efficiently at 56.3%.

Iva Jovic, 18 years old, United States, world no. 16, right-handed. The kid from Pasadena had never set foot on a court in Charleston before this week, and she has made herself at home there. Quarterfinal at the Australian Open in January, final in Hobart, and a week here that confirms this fast green clay suits her attacking game and 18-year-old legs perfectly. Yesterday against Kenin she closed it out 7-5 7-5, saving two match points, the sign of a player who handles the big moments.

The clay numbers over the last 52 weeks don’t leave much room for doubt. Match efficiency 2.598 versus 1.676, return games won 50.8% versus 34.8%, first-serve return points 46.4% versus 37.4%. Jovic is constantly breaking serve on this surface and dominates under pressure on return at every key score. The market is pricing in Kalinskaya’s past results in Charleston without seeing that the American gem is structurally above her on clay right now.
