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.
