Ostepinco is the first player to beat the five -time big champion Sweat at every level – once on the grass, four times on the harsh courts and now on the mud once.
Sweettas often struggle against the powerful ground strokes of Ostapinco, which advances its offer and make mistakes in its game.
The Qutb Stuttgart came into the match with an 11-1 record, which won the award in 2022 and 2023, but could not stop Ostapinco.
Ostepinco targeted 29 winners in 17 of the Sweet, eight double errors are not helping Sweat because OstaPenko attacked his second service.
Ostepinco broke the Sweet Service three times to take the first set but remained scripped in the second, which allowed Swetk to equalize the match.
But Ostepinco won 12 of the first 15 points of the decisive set to take control, eventually taking the match to a long switch offer.
The 27 -year -old said, “He is a great mud player but I also won the French (Open), so I can say the same thing about myself.”
“I have a lot of respect for her and her team, but whenever I step into court with her, it’s a war and I’m ready for it.”
Ostepinco will face the semi-finals against Russia’s Ekatrina Alexandova, which defeated the third seed Jessica Pigola 6-0 6-4.
