Roger Federer made an almost flawless start to his Australian Open preparation with a superb straight-sets win over Cameron Norrie as defending champions Switzerland beat Britain in the mixed teams Hopman Cup in Perth Sunday.

Federer, who has won the past two Australian Opens off opening his season in Perth, made an early statement in dismantling Norrie 6-1, 6-1 in under an hour in the men's singles, before Belinda Bencic secured the tie for the Swiss with a 6-2, 7-6 (7/0) win over Katie Boulter. The Swiss won the mixed doubles to complete a clean sweep of the tie. The 91st-ranked Norrie was coming off an impressive win over world number 15 Stefanos Tsitsipas the previous day, but had no answer to the brilliance of the Swiss maestro, ranked third in the world.
