Australia knocked the United States out of the Fed Cup on Sunday with a 3-2 quarterfinal win in North Carolina, as Ashleigh Barty and Priscilla Hon beat Danielle Collins and Nicole Melichar, 6-4, 7-5, in the deciding doubles match.
Barty had beaten Madison Keys, 6-4, 6-1, earlier to give Australia a 2-1 lead. Collins, who reached her first Grand Slam semifinal at the Australian Open last month, made it 2-2 after a 6-1, 3-6, 6-2 victory over Daria Gavrilova.
The Australians will next play Belarus, which lost the 2017 final to the United States, in April. Belarus dominated Germany at Braunschweig, with Aryna Sabalenka cruising past Laura Siegemund, 6-1, 6-1, to give her country an insurmountable 3-0 lead over the hosts on an indoor hard court.
Romania reached the semifinals with a 3-2 upset of the defending champion Czech Republic, rounding out the final four along with France, which defeated Belgium.
Romania made the semifinal round for the first time after its first victory against the Czechs, who won six titles in the last eight years.
Irina-Camelia Begu and Monica Niculescu teamed up to clinch the best-of-five series against their hosts with a 6-7 (2), 6-4, 6-4 win over the Czech pair Katerina Siniakova and Barbora Krejcikova, who won the mixed doubles title at the Australian Open with Rajeev Ram.
Romania took a 2-1 lead on an indoor hardcourt in Ostrava after Simona Halep defeated Karolina Pliskova 6-4, 5-7, 6-4 in a reverse singles match featuring two former top-ranked players. Halep improved her record against Pliskova to 7-2 as she put Romania one win from advancing.
Siniakova, the star of last year’s final victory against the United States, made it 2-2 after defeating Mihaela Burzanescu 6-4, 6-2.
In Liege, Caroline Garcia clinched an insurmountable 3-0 lead for France over host Belgium after easing past Elise Mertens, 6-2, 6-3, to set up a semifinal against Romania.
Garcia earned a couple of victories in her first Fed Cup action since the 2016 final, including beating Alison Van Uytvanck by 7-6 (2), 4-6, 6-2 in the opening singles on Saturday.
In the doubles, Ysaline Bonaventure and Kirsten Flipkens won a consolation point for Belgium with a 6-3, 3-6, 10-6 victory over Fiona Ferro and Pauline Parmentier to reduce the final score to 3-1 with the second reverse singles not played.
