For the fourth time this season, Marta Kostyuk and Mirra Andreeva face off with a spot in the quarterfinals of the WTA 1000 in Cincinnati on the line.

Since claiming her first Grand Slam title at the French Open, Mirra Andreeva has struggled to build on that victory. The young Russian has had a string of disappointing results, including a second-round exit at Wimbledon and a third-round exit in Toronto just recently. Her start to the tournament in Cincinnati has been strong, with two first-round victories that have allowed the No. 6-ranked player to find her rhythm in the American heat. Quick victories over Ukraine’s Oleksandra Oliynykova (6-1, 6-0) and Indonesia’s Janice Tien (6-1, 7-6) got Mirra Andreeva off to a strong start in Cincinnati.

Marta Kostyuk is a different player this year, having had a very solid season that has put her on the verge of the top 10. The Ukrainian has taken her game to a new level on clay and now hopes to replicate that success on hard courts, as she did at Wimbledon, where she reached the semifinals. This week in the United States, Marta Kostyuk had to work hard in a tough half of the draw. She secured victories over Americans Madison Keys (4-6, 6-3, 7-5) and Sloane Stephens (7-5, 7-5), showcasing her mental toughness in decisive moments in each match.
