Jessica Pegula and Taylor Townsend sent the United States into the Billie Jean King Cup semi-finals for the first time since 2021 after beating Kazakhstan 2-1 on Thursday.
Pegula and Townsend topped Yulia Putintseva and Elena Rybakina 6-2, 7-6 (1) in the deciding doubles.
In singles, Emma Navarro stunned Putintseva 7-5, 2-6, 7-6 (6) after saving two match points. Putintseva led 6-4 in the tiebreak but Navarro took the last four points after two-and-a-half hours.
Former Wimbledon champion Rybakina evened the quarterfinal by dispatching Pegula 6-4, 6-1 in a top-10 clash.
Pegula brushed off her first loss to Rybakina in two-and-a-half years by pairing with Townsend, the world doubles No1 and two-time major doubles champion, who created some controversy this week in comments about Chinese food.
Townsend dominated the first set and the U.S. pair strode through the second set tiebreak, winning on a Rybakina double fault.
"I wanted to kind of redeem myself a little bit out there against her (Rybakina), try and help my team get a win," Pegula said.
The U.S. will play Britain in the semifinals on Saturday.

In the other half of the draw, Ukraine faces defending champion Italy in the semifinals on Friday. Marta Kostyuk and Elina Svitolina won singles matches over Jessica Bouzas Maneiro and Paula Badosa, respectively, to put Ukraine through to the final four. Italy beat host China.
