Ageless Roger Federer warmed up for a run at a record seventh Australian Open title on Monday by breezing past Uzbek Denis Istomin in straight sets to book a spot in the second round.

The 37-year-old Swiss master made light of his assignment on Rod Laver Arena to wrap up the match 6-3, 6-4, 6-4 as he confidently began the defence of his title.
