San Francisco Frontiers - De Minaur's Australia trail as Germany, Argentina into Davis Cup finals

Germany and Argentina became the first two teams to qualify this weekend to join defending champions Italy in the eight-team final in Bologna in November.

Germany beat Japan 4-0 in Tokyo with Argentina taking an unassailable 3-0 lead against the Netherlands in Groningen.

The 23-year-old Collignon, ranked 91, overcame severe cramping at the Ken Rosewall Arena in Sydney to score a 7-5, 3-6, 6-3 upset after over three hours of play.

Belgium's number one Zizou Bergs then beat Jordan Thompson 7-6 (7/4), 6-4 in the other singles rubber.

It leaves 28-time champions Australia, who were runners-up in 2022 and 2023 and semi-finalists last year, needing to win both reverse singles and the doubles on Sunday.

Collignon was always going to be a tricky proposition for De Minaur after posting a career-best win over world number 12 Casper Ruud at the just-completed US Open en route to the third round.

Beating the Australian was his biggest scalp so far.

"It feels amazing, I thought I wouldn't be able to finish the match because I got cramp so bad at the beginning of the third," said Collignon.

"I tried to go for it, focus on the serve and I don't know how I won.

"I think when you play for your country there is no pain... I am very happy."

After the Belgian took the first set, De Minaur surged back with 10 consecutive points to take charge of the second and with Collignon doubling over with cramp in the first game of the third set, it appeared the Australian would bank the win.

But Collignon heroically battled on to give his country an unexpected advantage.

"It feels great for the team," said Bergs. "We did a great job today, but we are far from the end."

- Hungary, Croatia fight back -

In Tokyo, doubles duo Kevin Krawietz and Tim Puetz sealed the winning point for the Germans against Yosuke Watanuki and Takeru Yuzuki 6-3, 7-6 (7/4).

The Japanese pair dug deep, saving four match points in a tight tie-break before conceding to the three-time champions.

Justin Engel made it 4-0 after a 6-3, 6-7 (2/7), 10-7 battle with Rei Sakamoto.

Argentina's Andres Molteni and Horacio Zeballos sealed the winning point in the doubles against the Netherlands.

In Debrecen, Hungary rekindled their campaign pulling level 2-2 with Austria.

Fabian Marozsan and Zsombor Piros won a tight 7-6 (7/4), 7-6 (7/2) doubles tie against Austria's Alexander Erler and Lucas Miedler. Zsombor Piros then dispatched Lukas Neumayer 7-5, 7-6 (8/6) leaving all to play for in the final singles tie.

"We were the underdogs in the doubles," said Marozsan.

"But we made it and I think we still have a chance to come back and win this tie. We believe in ourselves."

In Osijek, Croatia also powered back against France with Nikola Mektic and Mate Pavic winning the doubles 6-3, 7-5. France lead 2-1.
