MALAGA, Spain (AFP) — Alex de Minaur smoothly guided Australia into a second successive Davis Cup final with an assured 2-0 win over Finland on Friday in Malaga.

The world No. 12 wore down Emil Ruusuvuori in a 6-4, 6-3 straight sets triumph, after Alexei Popyrin beat Otto Virtanen 7-6 (7/5), 6-2 in the first singles rubber.

Australia, who last won the competition in 2003, will face Novak Djokovic's Serbia or Jannik Sinner's Italy in Sunday's final.

"For us this cup is a priority, we do everything we can to represent Australia, with pride and passion," De Minaur said.

"It's not too bad to reach another final."

Australia captain Lleyton Hewitt said reaching the final means "a hell of a lot" to him.

"Our boys dug really deep… we're a tight-knit unit and we've given ourselves another opportunity on Sunday," he added.

De Minaur produced a remarkable comeback against the Czech Republic in a rollercoaster classic to help his country reach the semi-finals but had a gentler ride this time at the Martin Carpena arena.

Although he and Hewitt have been highly critical of the revamped Davis Cup format, the 24-year-old expertly steered his team into their 49th final.

The 28-time champions, behind only the United States, ended Finland's fairytale run with little fuss, and the captains agreed not to play the deciding doubles.

Nordic fans outnumbered those in green and gold, just as they did for their superb last eight victory over reigning champions Canada on Tuesday, but this time left disappointed.

Finland's number one, Ruusuvuori, 69th in the world, missed the Canada win with a shoulder problem and he had heavy lifting to do after Virtanen's defeat.

Ruusuvuori exchanged breaks with De Minaur, with the Australian finally converting his sixth break point in the third game to get back on serve and never looked back.
