Federer, Djokovic, Davydenko, Williams in Australian Open third round
MELBOURNE: Roger Federer and the Williams sisters stamped their authority on the Australian Open Thursday, but former world number one Ana Ivanovic was sent packing.
The Swiss world number one took his place in the third round with a straight sets demolition of hapless Romanian Victor Hanescu.
Watched by Britain''s Prince William, he dominated in the 6-2, 6-3, 6-2 rout.
Federer, bidding for his 16th Grand Slam title and fourth Australian Open, will now play Spanish 31st-seed Albert Montanes.
Defending champion Serena showed she was still the woman to beat, barely breaking a sweat as she crushed Petra Kvitova of the Czech Republic, 6-2, 6-1.
Much of the talk this year has been about the return of Belgian pair Kim Clijsters and Justine Henin, but Williams made clear that anyone who wants to lift the trophy will have a fight on their hands.
Sister Venus, a seven-time Grand Slam champion but yet to win in Melbourne, was more workmanlike, grinding down Austrian Sybille Bammer 6-2, 7-5.
Men''s third seed Novak Djokovic overcame some first set wobbles to ease past Swiss Marco Chiudinelli 3-6, 6-1, 6-1, 6-3 and set up a third round with Uzbekistan''s Denis Istomin.
More impressive was Russian sixth seed Nikolay Davydenko, who is shaping as a serious title contender after extending his win streak to 11 matches.
The 28-year-old has yet to win a Grand Slam and has never been in a final but his 6-3, 6-3, 6-0 disposal of Ukrainian Illya Marchenko served notice that his time may have come.
In other matches, Danish fourth seed Caroline Wozniacki breezed past Germany''s Julia Goerges 6-3, 6-1 while ninth-seeded Russian Vera Zvonereva had an easy 6-0, 6-3 win over Czech Iveta Benesova.
Former finalist Marcos Baghdatis of Cyprus advanced past David Ferrer 4-6, 3-6, 7-6 (7/4), 6-3, 6-1 and will next face Australian Lleyton Hewitt.
Ninth seed Fernando Verdasco and 10th seed Jo-Wilfried Tsonga also progressed.
