The world number two maintained an unblemished record in five clashes with the eighth-ranked Sock, beating the American in straight sets as Switzerland beat the United States 3-0 to advance to Saturday’s final. Belinda Bencic’s superb form continued when the world number 74 then upset 10th ranked CoCo Vandeweghe to secure the tie and put the Swiss into the final. The dead mixed doubles rubber was extremely light-hearted, with the Swiss winning in straight sets. He was only broken once, in the 11th game of the second set, after Federer produced some stunning defence under pressure. “He came up with an unbelievable point to break in the second set,” Sock said.
