ATP: Milos Raonic defeated by Mackenzie McDonald in Round of 16 in Toronto

TORONTO — Canada’s Milos Raonic was eliminated in the third round of the National Bank Open on Thursday.

Raonic lost in straight sets 6-3 6-3 to American Mackenzie McDonald at Sobis Arena.

The Canadian, who returned to the ATP tour in June after a nearly two-year absence due to injury, struggled against the world No. 59.

Raonic’s serve was not the same as usual and he committed 32 unforced errors compared to only 12 for the American. The former world number three was the last Canadian still to compete for the singles title.

Raonic swept the ninth seed, American Frances Tiafoe, in the first round, before defeating Japan’s Taro Daniel in the second round.

The 32-year-old Ontarian never looked relaxed despite cheering from fans around Center Court.

McDonald Raonic broke his first serve in both sets and was more consistent than his opponent. Leaving Raonic on his heels, the American occasionally worked with combination serves and volleys while relying on effective shots and good ball positions.

Raonic forced three match points late in the second set, but McDonald won his serve and closed the books in 68 minutes.

Play was suspended on all grounds for over an hour in the early afternoon due to rain and lightning.

McDonald will be in the first quarter-final of his career at the Masters 1000 Caliber. He will cross swords with Spaniard Alejandro Davidovich Fokina, who beat Norwegian Casper Ruud (No. 3) 7-6 (4), 4-6, 7-6 (4).
