Rybakina has a good record overall—36-14—but she has just one title, hasn’t made the quarters at a major, and is out of the Top 10 for the first time in three years. Kostyuk has had it worse. After showing improvement in 2024, her rise has stalled; she’s just 20-16 on the year, and is down form No. 16 to No. 28.

Elena Rybakina advanced to the semifinals of the Canadian Open after Marta Kostyuk retired in the second set. The Kazakh player was having a notable performance in Montreal and was ahead 6-1, 2-1 when the Ukrainian player withdrew from the match due to a wrist injury.
