Why the Odds Changed
Jelena Ostapenko is expected to take early control against Ella Seidel by claiming the opening set in their Roland Garros first-round meeting.
Recent Developments
Jelena Ostapenko is set to make a strong start in her Roland Garros clash with Germany’s Ella Seidel, with the former French Open champion widely expected to assert herself early on the Paris clay. The opening set is likely to be a key marker of the match, and Ostapenko’s aggressive baseline game gives her a clear path to seize the early advantage.
Ostapenko, who lifted the Roland Garros title in 2017, remains one of the most dangerous shot-makers in the women’s draw when her timing is sharp. Against Seidel, she is expected to dictate rallies from the outset, using her power on return and forehand to keep the younger German under sustained pressure.
Seidel will look to extend exchanges and test Ostapenko’s consistency, but the Latvian’s experience and first-strike tennis should position her to capture the first set and establish control of the match.
