Russia has three men in grand slam quarter-finals for the first time on Monday at the Australian Open.

This was after Daniil Medvedev and Andrey Rublev made it past Mackenzie McDonald and Casper Ruud respectively

Earlier, unseeded American Jessica Pegula upset fifth seed Elina Svitolina 6-4 3-6 6-3 to reach her first career grand slam quarter-final.

Second seed Rafael Nadal dismissed Italy’s Fabio Fognini 6-3, 6-4, 6-2 to reach the last eight in Melbourne for the 13th time.

Fourth seed Medvedev extended his winning streak to 18 matches with a straightforward win over unseeded American Mackenzie McDonald 6-4 6-2 6-3.

Rublev took the first two sets before his Norwegian opponent retired on 6-2 7-6 (7-3).

Reigning ATP Finals champion Medvedev and Rublev won the ATP Cup just over a week ago at Melbourne Park.

They now join compatriot Azlan Karazev in the last eight after the qualifier had the previous day come back from two sets down to upset 20th seed Felix Auger-Aliassime.

The three Russians had already achieved a grand slam first by all making it to the fourth round.

At least one Russian player will make it to the Melbourne semi-finals as Medvedev and Rublev are set to face off in the quarter-finals on Wednesday.

Twenty-time grand slam champion Nadal was yet to drop a set in Melbourne after defeating Italian 16th seed Fognini in two hours and 16 minutes.

The Spaniard will next face the winner of the match between Greece’s Stefanos Tsitsipas and Fognini’s compatriot Matteo Berrettini at Rod Laver Arena.

Earlier on the show court, unseeded American Jessica Pegula upset fifth seed Elina Svitolina 6-4 3-6 6-3 to reach her first career grand slam quarter-final.

Svitolina looked set for a comeback after digging herself out of an early break in the second set, having dropped the opener, to force a decider.

In the third set the American, ranked 61st in the world, continued to put pressure on the Ukrainian’s serve.

She eventually held a break of serve to take the win in just under two hours of play at Rod Laver Arena.

Pegula, whose presence in the fourth round of the Australian Open was her best grand slam result before Monday, will next face Jennifer Brady in an all-American quarter-final.

This was after the 22nd seed defeated Croatia’s Donna Vekic 6-1 7-5.
