Marta Kostyuk beat Ann Li in the quarterfinals. The match took 28 games to decide and lasted two hours and 4 minutes. Kostyuk was flawless in the opening set, which she won 6-0 in half an hour. She served for the match 6-5 in the second set, but was broken to 15. Li took the set to a tiebreak and won it 7-4.

In the deciding set, the American had all the momentum and led 3-1 with an early break. But Kostyuk reeled off five games in a row to turn it around and prevail. In the victory, Kostyuk hit 5 aces and 5 double faults. She landed 57% of first serves in play and won 78% of first serve points (38/49).

Before this round, Kostyuk had beaten Diane Parry 6-1, 6-4 and Caty McNally 2-6, 6-2, 6-1.

Tatjana Maria is through to her first semifinal of the season. Before this week, Maria had won three matches at all levels. But she’s doubled that tally at the Rouen Open, where she is making her tournament debut. The 38-year-old has not dropped a set. She won her opening match against Elsa Jacquemot 6-4, 6-3. In the second round, Maria defeated Dominika Salkova 6-3, 6-2.

Her quarterfinal victory over Irina Shymanovich was her toughest assignment so far, but Maria prevailed 7-6, 6-2. She needed five set points to close out in the opening set after an hour and 5 minutes. In the second set, Maria earned two breaks to wrap up a straight sets win. 

Marta Kostyuk vs Tatjana Maria Head-To-Head

Marta Kostyuk vs Tatjana Maria Prediction

Maria has not dropped a set this week, but faces the top seed Kostyuk and I just can’t see her getting through to her first final of the season. Kostyuk blitzed past the German in each of their two WTA meetings. The Ukrainian is a more experienced player than the caliber of opponents Maria has beaten this week, and has the offensive instinct to punish any short balls off that wicked slice. Give me Kostyuk for a straight-sets win.
