Marta Kostyuk and Li Ann are set to face off for the third time in their careers. They will go head-to-head in the quarter-finals at WTA Rouen to mark their first meeting on clay. We have a prediction for this match below.

After a win in straight sets in the opening round, top seed Kostyuk was made to work for her win in the second.

She managed to overcome Caty McNally but only after coming from a set down in a match that lasted close to two hours. Marching on to her second quarter-final of the season, Kostyuk is 25th in the live rankings.

Li has dropped a set in both of her matches here, and as a result, she’s spent one more hour on the courts. In her latest meeting with Kostyuk, she lost in three sets in San Diego in 2024, and revenge will be on her mind as well.

Like Kostyuk, Li is making her Rouen debut, and the fifth seed has already seen off Daria Kasatkina and Kamilla Rakhimova.

Playing in her first quarter-final of the season, Li is placed 33rd in the live rankings. Seven of her last 10 matches produced three sets, and she’s dropped at least one in each of her last nine outings.
