ANTWERP, Belgium — Canada's Milos Raonic has withdrawn from the European Open because of an abdominal strain.
The No. 5 seed, from Thornhill, Ont., was scheduled to face No. 4 seed Grigor Dimitrov of Bulgaria in a quarterfinal at the ATP Tour 250 hard-court event on Friday.
Dimitrov was awarded a walkover win and will face No. 8 seed Alex de Minaur of Australia or American Marcos Giron in the semifinals.
South African qualifier Lloyd Harris faces France's Ugo Humbert and No. 3 seed Karen Khachanov of Russia meets Great Britain's Daniel Evans in the other quarterfinals.
Plagued by injuries throughout his career, Raonic was coming off a run to the semifinals last week at a tournament in St. Petersburg, Russia. He is ranked 19th in the world.
