MONTREAL — Top-seeded defending champion Rafael Nadal of Spain advanced to the Rogers Cup final Saturday night when Gael Monfils of France withdrew before their semifinal.

Nadal will face eighth-seeded Daniil Medvedev, a 6-1, 7-6 (6) winner over sixth-seeded Karen Khachanov in the all-Russian first semifinal.

Monfils, seeded 16th, outlasted 10th-seeded Roberto Bautista Agut of Spain 6-4, 3-6, 7-6 (2) in a match suspended Friday night because of lightning. Monfils finally finished off Agut after a rain delay Saturday, but battled a sore left ankle that forced him to pull out of the semifinal.

Nadal won last year in Toronto for his fourth title in the event. He has 82 singles victories, winning the French Open in June for his second title of the year.
