Roger Federer secured another victory for Team Switzerland in the Hopman Cup on Thursday with a 7-6, 7-5 win over USA’s Jack Sock, while team-mate Belinda Bencic followed suit with a 7-6, 6-4 win over CoCo Vandeweghe.
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.
It was a hard-fought contest between Federer and Sock, with the pair producing just one break of serve in the whole match.
The Swiss maestro claimed an evenly matched first set via tiebreaker, with both players putting on a show of impressive serving.
Their opponent will be decided on Friday, with Germany and Belgium the leading contenders.
The dead mixed doubles rubber was extremely light-hearted, with the Swiss winning in straight sets.
Federer is aiming for a second Hopman Cup title, having also won the tournament back in 2001, before he had won an ATP singles title, when he partnered with Martina Hingis.
