Game context
Tereza Valentova, the higher-ranked Czech seed at No. 54 with a 16-13 record in 2026, faces Sofia Costoulas of Belgium, ranked No. 156, in the Athens Open round of 32 on outdoor hard courts. Valentova brings stronger recent main-tour experience, including a third-round run at the Australian Open and a WTA 125 final in Saint-Malo, while Costoulas has posted solid results primarily at ITF and WTA 125 levels with a 23-15 singles mark this year. Valentova leads their head-to-head 1-0 from a 2024 ITF meeting. Both players arrive after Wimbledon exits, with the hard-court surface and Valentova’s seeding positioning her as the consensus favorite, though Costoulas’s aggressive baseline game and recent doubles success offer upset potential in a first-edition WTA 250 event.
