Canadian dreams of a second straight singles champion at the national open have been dashed. Leylah Fernandez was eliminated from the National Bank Open presented by Rogers with a 6-4, 6-4 loss to Naomi Osaka in the Round of 16 on Sunday in Toronto. The 30th-seeded Fernandez, of Laval, Que., was the last Canadian remaining in either the men’s or women’s singles draws. Victoria Mboko, from Burlington, Ont., won the tournament last year but was unable to defend due to injury. Osaka, the 11th seed, will next face second-seeded Elena Rybakina in the quarterfinals.
