Russia and Canada booked their spots in the semi-finals of the ATP Cup on Thursday.
Russia completed their group stage campaign with a 2-1 victory over Italy in Group B.
The match was a winners take all clash with the Italians making the perfect start as Jannik Sinner defeated Roman Safiullin 7-6(8) 6-3.
However world number two Daniil Medvedev levelled the tie in a hard-fought victory over Wimbledon finalist Matteo Berrettini.
Medvedev needed 2 hours and 40 minutes to edge out Berrettini 6-2 6-7(5) 6-4 to put Russia level with Italy.
Then all four singles players returned for the doubles which the Russians won 5-7 6-4 10-5 in a tense contest.
This saw Russia book a place in the last four and after the match Medvedev spoke about the importance of his win over Berrettini, “The first set I was in control and it’s tricky because you think that things will continue to go your way but that’s not the case when you’re up against a Top 10 player,” Medvedev told the ATP Cup website.
“I made some bad decisions in the second set so I tried to learn from that in the third. I served well throughout the match and that helped me.”
Russia will now face Canada in the last four on Saturday after Denis Shapovalov and Felix Auger-Aliassime both secured singles wins over Germany.
Shapovalov edged out Struff in three sets to give Canada the lead and then Felix Auger-Aliassime scored a huge victory over Olympic champion Alexander Zverev 6-4 4-6 6-3.
This meant that Canada denied Great Britain a place in the semis after the Brits beat USA 2-1 earlier in the day. The other result saw Australia beat France 2-1.
