Rafa Nadal will play Russia’s Daniil Medvedev for the Rogers Cup title in Montreal on Sunday  after injured Frenchman Gael Monfils withdrew from his semi-final match with the Spanish top seed on Saturday.

Medvedev topped Karen Khachanov in an all-Russian semi-final before Monfils announced he was no shape to face Nadal a couple of hours after injuring his left ankle in a quarter-final win over Roberto Bautista Agut.

Eighth seed Medvedev prevailed 6-1 7-6(6) over Khachanov in a victory that will make him Russia’s top-ranked player on Monday.

Medvedev was upset after letting a break advantage slip away on two occasions in the second set, including at 5-4 as he tried to serve out the match.

He also allowed Khachanov to score four consecutive points after taking a 2-1 lead in the second set tiebreak.

But Medvedev, who has not lost a set in the tournament, fought back to tie at 4-4 and after two more ties won the final two points and the match.

Frenchman Monfils also needed to win a tie-break to defeat Bautista Agut in the third set of their rain-delayed quarter-final match.

Monfils won out 6-4 3-6 7-6(2) in a match that took two days to complete because of rain but the ankle injury was clearly hampering him and he withdrew from the tournament two hours later.

The ankle started bothering Monfils in the second set, but after a visit by a physio he elected to continue.

Bautista Agut won the set comfortably and the third went to a tie break which Monfils led 5-0 before sealing victory with a huge forehand winner after more than two hours. (Production: David Grip)
