Germany Advances to United Cup Semi-Finals Led by Zverev's Victories

Zverev's wins in singles and mixed doubles overturn Greece's initial lead, setting up a semi-final clash with Australia.

Alexander Zverev led Germany into the United Cup semi-finals after winning his singles match against Greece's Stefanos Tsitsipas and partnering with Laura Siegemund in the mixed doubles.
Maria Sakkari of Greece initially gave her team a 1-0 lead with a win over Angelique Kerber, but Zverev's victories turned the tide in Germany's favor.
Germany will now face Australia in the United Cup semi-finals.
Zverev, who is hoping to progress further in the Grand Slam this year following his recovery from an ankle injury, remains unbeaten in the season-opening mixed teams event.
France and Poland will compete in the other semi-final match.
