Siegemund/Zvonareva, who had never played together prior to this event, had total control over the match and defeated Melichar of the United States and Xu of China 6-4, 6-4 in 79 minutes.
"I felt very nervous when I played because we were behind at that time. Also, I like the atmosphere of the knockout round, it was intense, like in international events," said He Bingjiao after taking a straight win in the women's singles against Zhou Meng.
Evergrande doubled the lead in the 69th minute with a stunning free kick from Ai, two minutes after his tap-in was ruled out due to off-side.
Zall tried to add fresh attacking impetus by bringing loanee Dong Xuesheng and under-23 goalkeeper Wang Zhifeng on for the second half.
Fernandinho equalized after dribbling into the box and beating Hebei goalkeeper Bao Yaxiong, finishing a counterattack in the 29th minute.
Osaka then gained the momentum and broke a third time to take the match to a deciding set.
As the match moved deep into the fifth set, it became more about mental fortitude than technical skill. Zverev fought through nerves by moving forward and was rewarded by breaking Thiem at 4-3 with an aggressive forehand.
"I consider New York my second home, I really love the atmosphere, even though sadly there are no people here, I really feel this court really suits me well," Osaka said.
"Mary is our key player and his goals tell everything," said Shenzhen coach Jordi Cruijff. "His problem is not clear and we have to wait. I hope he will back soon because we have more games in very short period."
"We are continually grateful for the close relationship that we enjoy with the European Tour. By sharing insights with us on the ever-changing landscape of the international golf tournaments, we were able to make an informed decision to once again postpone the Magical Kenya Open to a more suitable time next year," said Peter Kanyago, the Chairman of Kenya Open Golf Limited said in a statement.
"We have extraordinary challenges ahead of us this season, and it will be a pleasure and an honour to face them alongside my new teammates, who are among the best players in the world," he added.
