Top-seeded Elena Rybakina continued her outstanding 2026 campaign by overwhelming sixth-seeded Mirra Andreeva 7-5, 6-1 on Saturday to reach the finals of the Porsche Tennis Grand Prix in Stuttgart, Germany.

Rybakina, who represents Kazakhstan, will face No. 7 seed Karolina Muchova of the Czech Republic in Sunday's final. Muchova pulled off a mild upset with a 6-4, 2-6, 6-4 victory over No. 4 Elina Svitolina of Ukraine.

Rybakina, who won the 2026 Australian Open and reached the finals at Indian Wells, exchanged breaks with Andreeva before winning four of five points on the Russian's serve to capture the first set. She cruised in the second set, winning a combined 21 of 25 points on her first serves and Andreeva's second service offerings.

The deciding set between Muchova and Svitolina looked to be going the distance, but the Czech won the final eight points of the match -- four on her opponent's serve in the ninth game -- to set up the fourth all-time meeting with Rybakina. Muchova has won two of three prior matches, including a quarterfinal victory in January at Brisbane.

Rouen Metropolitan Open

Top-seeded Marta Kostyuk of Ukraine cruised past Germany's Tatjana Maria 6-3, 6-0 to reach the finals in Rouen, France.

Kostyuk will take on teenage qualifier and countrywoman Veronika Podrez. She advanced in a walkover prior to her scheduled match against Romania's Sonia Cirstea, who withdrew due to a leg injury.

Kostyuk, who will be trying to win her second WTA title and first since a 2023 championship in Austin, Texas, fended off all four break points in the match against the 38-year old German. Maria could not contain Kostyuk's power, dropping 32 of 43 (74.4%) service points.

Podrez, 19, advanced to the semifinals with wins over Sloane Stephens, No. 7 seed Elisabetta Cocciaretto of Italy and Great Britain's Katie Boulter.
