Germany leans on reigning Olympic champion Alexander Zverev to capture United Cup

Reigning Olympic champion Alexander Zverev saved two match points in a remarkable comeback to win his singles tie in an epic three-setter and then helped clinch the United Cup final for Germany in the deciding mixed doubles match on Sunday in Sydney, Australia.

The sixth-ranked Zverev showed plenty of stamina in returning from the previous night's early morning finish to rally from a set down and two match points and defeat No. 9-ranked Hubert Hurkacz 6-7 (3-7), 7-6 (8-6), 6-4 in a three-hour epic at Ken Rosewall Arena.

Then playing his sixth match in three days, including a 2.20 a.m. local time finish on Sunday in Germany's marathon semifinal victory over Australia, Zverev partnered with Laura Siegemund to win the mixed doubles 6-4, 5-7, 10-4 in a super tiebreaker against Iga Swiatek and Hurkacz.

Fittingly, the winning shot was off Zverev's raquet as his backhand volley winner clinched for Germany what had appeared an unlikely United Cup title after nail-biting victories in the semifinal and in Sunday's final.

Earlier, top-ranked woman Swiatek had given Poland an early lead with a straight-sets win against Angelique Kerber.

Thre 22-year-old Swiatek beat Kerber 6-3, 6-0 in 70 minutes to stretch her win-streak to 16 matches, after the four-time major winner finished 2023 with title wins at the China Open and the WTA Finals in Mexico.

Swiatek's victory meant Poland needed just one more win from the remaining men's singles or mixed doubles match to claim the United Cup.

Hurkacz appeared to have Poland well on the way for its maiden team title as he led Zverev by a set and 6-4 in the second set tiebreaker.

Somehow Zverev found the energy and a superb running cross-court forehand that clipped the line to keep Germany in the
