Daniil Medvedev rolled into his second straight semi-final at the US Open on Wednesday, with the Russian advancing without facing a break point.
The 2019 finalist against Rafael Nadal took down compatriot Andrey Rublev 7-6(6), 3-6, 7-6(5) in two and a half hours to remain undefeated against his compatriot over three matches at the ATP level.
Medvedev was treated on his shoulder near the end as his level drifted slightly in the final set, though he moved through without problems in the end.
“It was toughest at the end,” the winner said. “This was the first time in a year that I actually celebrated a victory.
“I felt all along I could get into trouble, I was happy to just get the win.
Andrey was playing unbelievably, I’m really happy to go through – it was a very tactical match today.”
The two were the first Russians to play the quarters at a Grand Slam since Igor Andreev and Nikolay Davydenko at 2007 Roland Garros; Davydenko and Mikhail Youzhny met at this stage here a year earlier.
Rublev came into the contest with 19 wins this virus-shortened season, standing second on the ATP to the 26 of Novak Djokovic.
Rublev smashed a racquet after letting go of a 5-1 lead in the first-set tiebreaker as his compatriot took the early lead.
Rublev failed to convert on three set points before Medvedev got his chance, taking it with an ace to seize the set after 65 minutes as he won the last five points of the tiebreaker.
The match had been halted earlier for seven minutes with Rublev leading 6-5 on games as much of the power on the empty Ashe court failed, possibly due to a storm moving closer to the New York area.
Once it got re-started the Hawk-eye electronic line-calling system remained out of order for a period while all monitors in the stadium stayed black .
Medvedev began to gain control with a break for 4-2, with Rublev letting his emotions flow with a few primal screams as his longtime rival moved into 5-2 command.
Two games later, Medvedev took a 2-0 lead as he won the second set in barely half an hour.
In the third set, Medvedev was seen by the trainer while trailing 5-6 and receiving a shoulder massage.
Medvedev wrapped it up with another tiebreaker to complete a straight-set sweep for his final four place thanks to a match point brought on by a sitter ball which allowed an easy putaway.
