Serena Williams launched her latest bid for a record-equalling 24th Grand Slam with a 56-minute demolition of Laura Siegemund at the Australian Open.
Williams made a nervy start against Siegemund, double-faulting on the first point of the match before losing her opening service game.
US Open champion Naomi Osaka also made a convincing start with a 6-1 6-2 win over Russia's Anastasia Pavlyuchenkova.
But former champion Angelique Kerber was the first seed to be knocked out.
