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.

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.
