Olympic singles run comes to an end for Canada's Fernandez after 3rd-round loss to Kerber

Canada's Leylah Fernandez saw her run in the Olympic women's singles tournament come to an end on Tuesday, falling to Germany's Angelique Kerber in the third round at Roland-Garros Stadium in Paris.

Fernandez, the 16th seed, was ousted by the three-time major winner in straight sets, 6-4, 6-3. 

The 36-year-old Kerber, who upset Naomi Osaka in the first round, plans to retire after the Games.

Fernandez, 21, still has matches to play in Paris, competing alongside Ottawa's Gabriela Dabrowski in women's doubles and Montreal's Felix Auger-Aliassime in mixed doubles. She and Dabrowski won their opening match on Monday, while her mixed doubles opener is set for later Tuesday.

The Laval, Que., native outlasted Czech Karolina Muchova in the first round of singles before claiming a straight-sets win over Spain's Cristina Busca in the second round.

Auger-Aliassime, the men's 13th seed, is currently facing Germany's Maximilian Marterer in the second round.
