Tenth seed Marta Kostyuk and seventh seed Iga Swiatek will meet in the fourth round of the 2026 Canadian Open. This is their second meeting of the season and fifth overall. Swiatek has won three of the previous four meetings, and this prediction backs her.
Kostyuk defeated Swiatek back in May during a spectacular clay season. She won in straight sets at the French Open, ending Swiatek’s quest for another title in Paris.
As she has had a strong week and is one of the best performers this year, the Ukrainian will be confident of another victory. Kostyuk has won 30 of 36 matches this term, and this has led to two titles and an exponential rise in the world rankings.
Currently the 11th-best-ranked player in the WTA, Kostyuk defeated 19th seed Madison Keys in straight sets in the last round.
Iga Swiatek had won three straight meetings with Kostyuk before their meeting at Roland Garros. Twice she had won on a hard surface, and in one of those instances, she went on to win the title.
The former world number one, after having a strong week so far, will arrive confident of returning to winning ways. Swiatek, who is seeking her first title of the season, defeated Viktorija Golubic in straight sets in the previous round.
Though having compiled a strong 25-12 record, she is having a poor season by her standards. This has affected her world ranking, leading to her dropping to eighth in the WTA.
