Defending men's champion Novak Djokovic has marked his first appearance at this year's Australian Open with a brutal three-set thrashing of Italian Paolo Lorenzi to join No.5 seed David Ferrer in the second round.
Djokovic reeled off the final 17 games of the match after the Italian had the temerity to break him early in the first set, winning 6-2 6-0 6-0 in a clash on Rod Laver Arena which lasted an hour at 32 minutes.
It was high level tennis from the man who won three of the four Grand Slams last year, as he hit 22 winners and made just 13 unforced errors.
Lorenzi broke in the third game of the first set to lead 2-1, but never got a look after that point as the Serbian broke him in the fourth, sixth and then the eighth and final game of the first set when the Italian double faulted.
Djokovic had a sniff of a quick kill and reeled off three further breaks in the second and three more in the third, which he won in just 23 minutes.
Colombian Santiago Giraldo, who easily outpointed Italian Matteo Viola to make the second round of this tournament for the third consecutive year, is next for Djokovic.
Ferrer made similarly light work of his first-up assignment, demolishing Portugal's Rui Machada in straight sets.
Ferrer, a semi-finalist in Melbourne 12 months ago, looked in supreme touch as he vanquished the world No.70 6-1 6-4 6-2 in an hour and 44 minutes.
The Spaniard broke Machado in the fourth and sixth games of the first set to set the standard for the match, racing to a one-set lead in just 32 minutes on the back of seven winners.
Machado broke back in the second game of the second set, but Ferrer fired back, as unforced errors handed the advantage back to the fifth seed in the seventh and ninth games, and he took a vice-like hold of the match.
Breaks in the first and third game then set Ferrer well on his way to a second-round clash with either Ryan Sweeting or Matthais Bachinger, and he wrapped up the third set in just 28 minutes.
In other results, No.17 seed Richard Gasquet had a minor blip against Italian Andreas Seppi, before winning 6-3 3-6 6-3 6-1.
Lower profile seeds Milos Ranic (23), Kei Nishikori (24) and Alex Bogomolov Jr (32) also made progress early on Tuesday.
Japan's Nishikori got past France's Stephane Robert in three sets, 6-1 7-6 (9-7) 6-0, while Bogomolov Jr, now represented Russia, had a similarly easy time against Spain's Daniel Gimeno-Traver.
Raonic, one of the tour's rising stars, eased through 6-4 6-0 6-2 past Filippo Volandri and the Canadian now plays , Germany's Philipp Petzschner thrashed Czech Lukas Rosol, dropping just two games.
France's Edouard Rogers-Vasselin was handed passage through to the final 64 when Belgian veteran Xavier Malisse retired after losing a first set tie-breaker.
