10th seed Marta Kostyuk will lock horns with Madison Keys in the third round of the Canadian Open 2026.

After a first-round bye, Kostyuk commenced her campaign against Katherine Sebov. The Ukrainian dug herself out of a 4-1 hole in the first set to level the score, and overturned another break deficit after that.

The set eventually went to a tie-break, which went Kostyuk‘s way. The second set was over in a flash. Kostyuk swept six games on the trot to register a 7-6 (4), 6-0 victory.

Following a first-round bye, Keys faced Antonia Ruzic in the second round. The American conceded only one game in the first set to capture it without a fuss. The pair broke each other’s serve to kick off the second set. Keys took control of the match once again after the initial back-and-forth. She bagged five of the next six games to tally an easy 6-1, 6-2 win.

After staging a comeback to claim the first set, Kostyuk wrapped up the match in dominant fashion. She tallied her 29th win of the season against just six losses. She has a 7-4 record on hardcourts. She sustained an injury which led to a first-round exit from the Australian Open and it impacted the remainder of her hardcourt swing at the start of the season.

Keys’s easy win over Ruzic improved her record for the season to 26-11. It also marked her ninth win on hardcourts. She lost to Simona Halep in the final of the Canadian Open 2016, and made the quarterfinals last year. She has an 11-7 record at the tournament.

Kostyuk made the quarterfinals of the Canadian Open a year ago, her best result so far. She lost both of her prior matches against Keys in straight sets. Both of those matches took place at Wimbledon. However, Kostyuk is the middle of a career-best season.

Kostyuk has won 22 of her last 24 matches. She hasn’t lost prior to the semifinals of a tournament since her third-round loss to Elena Rybakina at the Miami Open. Keys, on the other hand, has a 0-3 record against top 20 players on hardcourts this season. She may not be able to maintain her perfect record against Kostyuk given the latter’s form over the past few months.

Pick: Marta Kostyuk to win in straight sets.
