PARIS, France (AFP) — Alexander Zverev defeated three-time major winner Stan Wawrinka in the Davis Cup on Friday as the German star returned to the courts for the first time since being cleared of domestic abuse.

The 25-year-old Zverev swept past Wawrinka 6-4, 6-1 in Trier to bring Germany level with Switzerland after the opening day of their qualifier.

On Tuesday, Zverev was told by the ATP that there was "insufficient evidence" to substantiate allegations against him of abusing a former girlfriend.

Former world number two Zverev always denied the claims, describing them as "baseless."

On Friday, Wawrinka, who helped his country win the 2014 Davis Cup, was returning to the team competition for the first time in eight years.

Now ranked 135 in the world, he was comfortably beaten for the fifth time in five meetings by Zverev.

"I think it's important to go into tomorrow's ties with a 1-1 scoreline," said Zverev after recording just a second match win in eight months.

He missed the last six months of the 2022 season having suffered ankle ligament damage in June during a French Open semi-final defeat to Rafael Nadal.

"That was the best match since my injury. It's going in a positive way and I hope to continue progressing."

Marc-Andrea Huesler had given Switzerland the lead with a 2-6, 6-2, 6-4 win over Oscar Otte.

The tie continues on Saturday with a doubles and two singles rubbers as the Swiss look to beat Germany for the first time having lost all nine meetings since their maiden clash in 1939.

Mackenzie McDonald and Tommy Paul gave the United States a 2-0 lead in their qualifier against Uzbekistan.
