Raonic's National Bank Open run halted in 3rd round by unseeded American

Canada's Milos Raonic is making a third-round exit at the National Bank Open.

He dropped a 6-3, 6-3 decision to American Mackenzie McDonald at Sobeys Stadium.

Raonic, from Thornhill, Ont., had his serve broken to open each set.

Raonic upset ninth-seeded American Frances Tiafoe in the first round of his hometown tournament and beat Japanese qualifier Taro Daniel in the second round.

Raonic was the last Canadian remaining in the singles draw of the Masters 1000 series event.

At the women's tournament in Montreal, third-round play is delayed due to rain.

World No. 1 Iga Swiatek was tied at one set apiece with No. 14 seed Karolina Muchova before the match was interrupted.

No. 10 Daria Kasatkina was leading Marie Bouzkova 2-1 in the second set after taking the first.

Tournament officials say play will not resume before 4:30 p.m. ET.

Leylah Fernandez of Laval, Que., who won an epic match over No. 11 seed Beatriz Haddad Maia on Wednesday, was scheduled to face American Danielle Collins at IGA Stadium's Centre Court on Thursday night.

Earlier Thursday, Jessica Pegula of the United States advanced to the quarterfinals with a 6-4, 6-0 win over Italy's Jasmine Paolini.

Pegula, the fourth seed in Montreal, had six aces to one double-fault and broke Paolini five times on 11 chances to cruise to victory in just one hour nine minutes.

The American is looking for her first NBO Open title after reaching the semifinals at the last two tournaments.

Pegula will next face the winner of a match between sixth seed Coco Gauff of the United States and ninth seed Marketa Vondrousova of Czechia.
