Roger Federer kickstarted the new tennis season by helping Switzerland to a 3-0 win over Japan in the Hopman Cup on Saturday.
He coasted past Yuichi Sugita in his singles match before his team-mate Belinda Bencic followed suit against Naomi Osaka, giving the Swiss an unassailable two-point lead. They clinched a whitewash with a narrow win in the doubles.
Earlier in the day, the United States picked up a 2-1 victory over Russia, with Jack Sock and Coco Vandeweghe winning their singles matches to secure the win.
Federer was forced to save a break point in his first game, and shanked a forehand into the crowd during the opening set before breaking world No 40 Sugita in the fifth game.
Despite the easy win, Federer was rusty at times, and he said it was nice to dust off the cobwebs in his first tournament since playing in the ATP World Tour Finals in mid-November.
