Roger Federer has recovered from a set down against Simone Bolelli to seal passage into the Australian Open third round.
The world No.2 was slow out of the gates in his 3-6 6-3 6-2 6-2 win but quickly found his rhythm to make the last 32 for the 16th straight year.
Federer joins Andy Murray, Tomas Berdych and Grigor Dimitrov in the third round in a day of few surprises at Melbourne Park.
