Teams are allowed to make doubles lineup changes after the singles matches are complete.

“The Finnish team played extremely well,” said Canada captain Frank Dancevic “Ultimately when you have injured players on one side, fresh guys who are confident on the other side who have never been in that situation before, they’re hungry, they had a big crowd, they ended up playing well in the end and getting through.” He opened with a 6-3, 7-5 victory over Finland’s Patrick Kaukovalta.

Instead, Milos Raonic of Thornhil, Ont., was pressed into singles action in his first Davis Cup appearance since 2018. Montreal’s Felix Auger-Aliassime clinched Canada’s first-ever Davis Cup title last year but he remained on the bench this time around due to a lower-body issue. Finland will play the winner of Wednesday’s quarterfinal between Czechia and Australia in the semifinal on Friday.
