SYDNEY, Australia (AFP) — Five-time Grand Slam champion Iga Swiatek beat Elena Rybakina in straight sets to take Poland into the final of the mixed-teams United Cup on Saturday with victory over Kazakhstan.

Last year’s runners-up will meet either a United States team led by Coco Gauff, or the Czech Republic on Sunday for the title in Sydney.

“This win makes me really proud,” Swiatek said after seeing off Rybakina 7-6 (7/5), 6-4 to give Poland an unassailable 2-0 lead in the tie.

It was a real statement of intent from the world number two with the first major of the year starting on 12 January.

“It is perfect preparation for the Australian Open,” the Pole said.

Swiatek again played with strapping on her right thigh, having been troubled in her tough three-set win over Britain’s Katie Boulter in the quarter-finals.

That clash lasted nearly three hours and Swiatek was slow out of the blocks against Rybakina, who is ranked sixth in the world.

They went to a first-set tie break after Rybakina saved two set points, before the 23-year-old Pole pulled away to take her country into the final.

“I for sure did not start well and had the handbrake on a bit. I knew I had to do something and change the momentum,” Swiatek said.

“I told myself I am not going to miss any more. For sure it was tough, it’s always tough against Elena.”
