Volkswacht Bodensee - Davis Cup heavyweights Australia, Spain, France and US into finals

Lleyton Hewitt's Australians went into day two tied 1-1 with Hungary and were fighting an uphill battle after Fabian Marozsan and Mate Valkusz upset John Peers and Luke Saville to clinch the doubles 6-4, 6-4.

That left world number 30 Alex de Minaur needing to win against 35th-ranked Marton Fucsovics to keep the clash alive -- and backed by a rowdy crowd at Sydney's Ken Rosewall Arena he battled through 7-6 (7/4), 6-4.

Kokkinakis last played in the Davis Cup seven years ago, but was recalled after claiming a first ATP singles title in Adelaide this year, then winning the Australian Open doubles crown with Nick Kyrgios.

With the tie on the line, he repaid skipper Hewitt's faith with a gutsy 6-4, 6-4 win over young Hungarian number two Zsombor Piros.

"Thank you Lleyton for trusting me, it's been a long time since I played and to play a fifth rubber at home has been incredible," he said.

Six-time champions Spain, playing without Rafael Nadal, advanced after world number 15 Roberto Bautista Agut gave his team an unassailable 3-1 lead over Romania with a 6-2, 6-3 victory over Marius Copil.

After losing their two opening singles matches on Friday, Romania kept their hopes alive by winning the doubles rubber, Copil and Horia Tecau defeating Alejandro Davidovich Fokina and Pedro Martinez 7-6 (7/2), 6-4 in Marbella.

But world number 261 Copil was unable to overcome the impressive Bautista Agut, who faced only two break points in the match.

"Bautista Agut did not lose a single easy ball, he played phenomenal," said Spain skipper Sergi Bruguera.

France, 10-time Davis Cup champions, were also untroubled as Pierre-Hugues Herbert and Nicolas Mahut defeated Gonzalo Escobar and Diego Hidalgo 6-3, 7-5 in Pau for a 3-0 win over Ecuador.

Record 32-time winners the United States of America enjoyed a 3-0 win over Colombia in Reno when Jack Sock and Rajeev Ram defeated Nicolas Barrientos and Juan-Sebastian Cabal 6-3, 6-4.

Argentina, champions in 2016, wrapped up a 3-0 win over three-time winners Czech Republic in Buenos Aires when Horacio Zeballos and Maximo Gonzalez defeated rookies Jiri Lehecka and Tomas Machac 6-4, 6-4.

The Netherlands exploited the weaknesses of a Canada side missing top-15 stars Felix Auger-Aliassime and Denis Shapovalov to coast to victory, secured by Robin Haase who racked up the 32nd Davis Cup singles win of his career courtesy of a 6-1, 6-2 victory against Steven Diez.

Defending champions Russia may have been banned but there will be Russian players in the next stage after Kazakhstan defeated Norway 3-1 in Oslo.

Russian-born Alexander Bublik sealed the win by defeating world number eight Casper Ruud 6-4, 5-7, 6-4.

Bublik also won his opening singles rubber on Friday while fellow Russia native Andrey Golubev and Crimea-born Aleksandr Nedovyesov claimed the doubles.

Elsewhere, Italy edged Slovakia 3-2, Belgium defeated Finland, Sweden saw off Japan, South Korea got the better of Austria while world number three Alexander Zverev won his second singles rubber of the weekend as Germany defeated Brazil in Rio.

Zverev saw off Thiago Monteiro 6-1, 7-5 for the winning point.

The 12 winners all progress to the finals, the first stage of which will be played in September with 16 teams involved.

Croatia, Great Britain and Serbia are already through, with Davis Cup chiefs to decide next week who will replace Russia after they were axed over the invasion of Ukraine.

Those 16 will be whittled down to eight for the quarter-finals in November.
