World number one Roger Federer produced an imperious display to dismiss unseeded German Florian Mayer 6-1, 6-4, 6-0 in the second round of the Australian Open on Thursday.
Sixth seed Guillermo Coria outslugged Italy's Federico Luzzi 7-6, 6-4, 6-3 in a baseline-dominated second round match while Russia's Nikolay Davydenko advanced to the third round of the Australian Open with a 4-6, 6-0, 6-3, 6-2 victory over Kevin Kim.
The Swiss top seed is widely tipped to win his second title in Melbourne and underlined that favouritism by crushing Mayer in just 72 minutes on Rod Laver Arena, finishing the German off with an ace down the centre of the court.
Federer is yet to drop a set in the tournament and produced another performance of power and precision, his backhand especially a constant threat to the outclassed Mayer.
The Swiss broke Mayer's serve six times in what amounted to little more than a workout and he moves on to a third-round encounter against either 30th seed Max Mirnyi of Belarus or Italy's Davide Sanguinetti.
World number nine Coria and lucky loser Luzzi took almost three hours to complete the three-set match before the Argentine eventually booked his place in the last 32.
Coria needed all five sets to overcome Romania's Victor Hanescu in the opening round and appeared on course for another drawn-out clash against Luzzi after the first set lasted 74 minutes, with the tiebreak going to 22points.
Theeighth game of the second set typified the first two sets with Coria holding seven break points only for Luzzi to fight off each one in scrambling baseline rallies.
The former French Open finalist managed to break Luzzi in the 10th game of the set for a 2-0 lead before cantering away with the third to set up a clash with either 25th-seededFrenchman Sebastien Grosjean or compatriot Juan Monaco.
Davydenko, who needed five sets to beat giant Croat Ivo Karlovic in the first round, dropped the first against the 99th-ranked Kim in a tough 52-minutebattle.
The 24-year-old Russian, however, clicked into gear in the second and ran away with it 20minutes, while the remaining two sets lasted not much longer. Davydenko sealed his third round match with either Australia's Nathan Healey or Amer Delic of the U.S. when Kim's forehand sailed long over the baseline on the Russian's second match point after two hours 14 minutes.
