The Ostapenko vs Valentova match in the Adelaide (W) tournament is set to be played at Memorial Drive Tennis Centre in Adelaide, Australia. The venue features outdoor hard courts, a main show court with a capacity of roughly 5,000–8,000 spectators, and recently upgraded facilities that regularly host WTA and ATP lead-up events to the Australian Open.

Given Ostapenko’s powerful baseline game, proven success on Australian hard courts, and consistent performance at WTA 500 level, the most likely outcome is a straight-sets win for her, with projected odds near 1.30 on the moneyline and 1.80–1.90 for a -4.5 game handicap. Valentova’s best value angle lies in over-games markets if she can extend rallies, but statistical form and ranking strongly favor an Ostapenko cover of the main handicap line.

Jelena Ostapenko and Tereza Valentova have not met previously on the main WTA Tour, so their official head-to-head record stands at 0–0.
