Iga Swiatek vs Marta Kostyuk prediction
Swiatek put up another strong performance to make the fourth round of the Canadian Open for the second year in a row. She hasn’t lost a set this week, and has conceded only six games across her two matches. She now has a 25-12 record this year, and a 14-6 record on hardcourts.
Kostyuk put her best foot forward to dispatch Keys. She didn’t drop her serve even once and saved all four break points that she faced. It marked her 30th win of the season against just six losses. She has also reached the fourth round in Canada for the second successive year.
Kostyuk tallied her very first win over Swiatek at the French Open a few months ago. The latter won their first three meetings in straight sets, including two on hardcourts. However, Swiatek has struggled against quality opposition this year. She has a 1-4 record against top 20 players on hardcourts this season, and has lost six of her last seven matches against them on the surface.
Kostyuk, on the other hand, has a 3-3 record against top 20 players on hardcourts in 2026. Two of those losses were against Elena Rybakina, and one against Aryna Sabalenka. Despite Swiatek’s past success in this rivalry, Kostyuk’s current form makes her the favorite to win their latest showdown.
Pick: Marta Kostyuk to win in straight sets.
