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.

Federer opened the match with an ace, giving his opponent an idea of what was to come, putting Sock under pressure to make a number of unforced errors in the opening set. Nonetheless, the American held out to a tie-break, eventually losing.

Sock put up a good effort against the former world no.1 but Federer was back on form in the second set, and able to serve out the set to win, despite a few errors on his part.

In previous rounds, Team Switzerland claimed clean sweeps against both Japan and Russia.

Still to come on Thursday, Federer’s team-mate Belinda Bencic will play CoCo Vandeweghe before the mixed doubles match between USA and Switzerland.
