Three-time Grand Slam winner Stan Wawrinka rolled back the clock to secure a thrilling win for Switzerland over Germany in their Davis Cup qualifier on Saturday.

The 37-year-old, part of the Swiss 2014 Davis Cup winning team but who had not played in the event since 2015, beat Daniel Altmaier 6-3 5-7 6-4 to seal a 3-2 win in Trier.

It was Wawrinka's first win of the tie after losing to Alexander Zverev on Friday and the doubles on Saturday.

Switzerland will now grab one of the 12 spots up for grabs for the 2023 Davis Cup Finals group stage in September.

A busy weekend of ties had 24 nations competing with the 12 winners joining 2022 champions Canada, runners-up Australia and wildcards Spain and Italy.

Switzerland had looked to be heading for defeat when Wawrinka and Dominic Stricker lost to Tim Puetz and Andreas Mies to give Germany a 2-1 advantage.

"I'm very happy I won the point, and the last one was the most important," Wawrinka, now ranked 135th in the world, said.

"I was happy to come back if they need me to help."
