Iga Swiatek beat Paula Badosa in three sets and Poland led Spain by an insurmountable 2-0 in the opening round of the Billie Jean King Cup Finals on Friday.
The world No. 2 Swiatek sealed Poland's spot in the quarterfinals against the Czech Republic after No. 12 Badosa was beaten 6-3, 6-7 7, 6-1 on the indoor hard-court.
Badosa scrapped to get back in the match by winning the second-set tiebreaker. But Swiatek roared back with a dominant third set and a break advantage of 8-3.
The match was delayed late in the third set for what organizers called a "medical incident" that apparently took place among the spectators inside Malaga's Palacio de Deportes.
"She pushed me," Swiatek said. "There was a lot of pressure in the tiebreaker and it went her way, but I knew I could get back in it in the third set."
