Lexus ATP Head2Head: Alexander Zverev and Laura Siegemund continued their perfect United Cup record in the mixed doubles on Monday, securing defending champions Germany’s status as Group E winners and a place in the quarterfinals with a victory against China in Group E.

The duo notched a 6-2, 7-6(3) victory over Zhang Zhizhen and Zhang Shuai in the deciding mixed doubles rubber against China, sealing a 2-1 win in favour of the defending champions. Zverev and Siegemund had won each of the four previous mixed doubles rubbers they contested at the event and ensured they kept a clean slate with a rock-solid performance, booking a quarter-final clash with Kazakhstan.

“Triple ZZZ is a very funny guy, we had a great singles and great mixed doubles match with Laura,” said Zverev. “I’m happy that we’re in the quarterfinals and, actually, I’m happy that China are in the quarterfinals too. Congratulations to the Chinese team. It was a really great match,” Siegemund added. “When you play for the first time after a while, you never really know what’s going to happen, and I think it was a great performance.”
