The last man to face, and beat, Rafael Nadal in professional tennis, 80th-ranked Botic van de Zandschulp, converted his 10th match point Friday to finally close out a 6-4, 6-7 (12), 6-3 victory over Daniel Altmaier and help the Netherlands reach its first Davis Cup final by sweeping Germany.

Tallon Griekspoor, who is ranked 40th, sealed the 2-0 win for the Dutch in the best-of-three-match semifinal by hitting 25 aces and coming back to defeat Jan-Lennard Struff 6-7 (4), 7-5, 6-4. When it ended, appropriately, on an ace, Griekspoor shut his eyes, dropped to his knees and spread his arms wide.

"We have been talking about this for two, three years," Griekspoor said. "We believed in ourselves so much. We always felt like this was possible. To do it now feels unbelievable."

The other semifinal is Saturday, with No. 1-ranked Jannik Sinner and defending champion Italy taking on Australia in Malaga, Spain. The championship will be decided Sunday.

"We don't have that top-five player. We don't that top-10 player. We don't have that top-15 player," Dutch captain Paul Harhuuis said. "But it's a team effort. So proud of these guys."

In Friday's opener, van de Zandschulp was up a set and just a point away from leading 5-2 in the second when Altmaier began playing more aggressively and interacting more with the German fans, yelling and throwing uppercuts or raising his arms after key points. In the tiebreaker, Altmaier managed to save five match points before converting his own fourth set point to extend the contest.

But van de Zandschulp, who upset four-time Grand Slam champion Carlos Alcaraz at the U.S. Open, quickly moved out front in the final set, even if he eventually needed five more match points in the last game before serving it out.

"At some point, I didn't know what to do any more on the match points," van de Zandschulp said. "I had the toughest match of my life on Tuesday [against Nadal] so everything that comes next is maybe a little bit easier."

In the quarterfinals, van de Zandschulp outplayed Nadal for a 6-4, 6-4 result that marked the end of the 22-time Grand Slam champion's career because the Netherlands went on to eliminate Spain 2-1.

The 38-year-old Nadal announced last month the Davis Cup would be his final event before retiring.

Presumably because people purchased tickets ahead of time with plans to watch Nadal compete in the semifinals, there were hundreds of unoccupied blue or gray seats surrounding the indoor hard court at the Palacio de Deportes Jose Maria Martina Carpena in southern Spain on Friday.

Now truly a neutral site, the place was not nearly as loud and rowdy as on Tuesday, although there were shouts of "Vamos, Rafa!" that drew laughter while van de Zandschulp played the 88th-ranked Altmaier.

It took Griekspoor more than 75 minutes and nearly two full sets to figure out how to break No. 43 Struff and then did it twice in a row to lead 6-5 in the second set, and then go up 1-0 in the third. That was plenty, because Griekspoor saved the only two break points he faced.

The Netherlands hadn't been to the semifinals since 2001. The Germans, whose best current player, two-time major finalist Alexander Zverev, is not on the team in Malaga, have won three Davis Cups, but not since 1993, when 1991 Wimbledon champion Michael Stich led them to the title.
