Nadal leads early charge of top seeds Down Under

MELBOURNE, (Reuters) – Rafa Nadal struck a blow  for the old establishment, overwhelming Lukas Lacko to become  the first man into the Australian Open’s last 16 last night,  before Caroline Wozniacki’s reign as world number one survived  with a win over Romania’s Monica Niculescu.

With the prime-time evening slot handed to 37th-ranked local  teenager Bernard Tomic, Rafa Nadal raised the curtain on an  intriguing Rod Laver Arena double-feature with Roger Federer by  pushing his Slovakian opponent off stage in less than two hours  with a 6-2 6-4 6-2 romp.

The 2009 champion Nadal came to Melbourne saddled with  doubts about his form, fitness and motivation, but has not lost  a set this tournament and never appeared in danger against his  119th-ranked opponent under overcast skies on centre court.

Hustling to chase down every point, it took a low-flying  bird swooping across the court to stall the Mallorcan’s charge  momentarily before he went on to close out the match with a  dominant service game.

Nadal set up a fourth-round clash with either big-serving  American John Isner or fellow Spaniard Feliciano Lopez. His  great rival Federer looms as a potential semi-final opponent.

The 10-times grand slam champion was asked hypothetically  what he would take from the Swiss maestro given the chance, and  answered simply: “We’re going to take the serve.”

With Rod Laver Arena occupied by Federer’s third-round clash  with Croatia’s Ivo Karlovic, Wozniacki’s battle for credibility  continued at Hisense Arena against 31st seed Niculescu.

With three other players able to snatch her top ranking at  Melbourne Park, the 21-year-old Dane signalled we should not  give up the prize without an almighty fight as she steamrolled  the Romanian 6-2 6-2 in 76 minutes.

Wozniacki will play the winner of American Christina McHale  and Serb Jelena Jankovic, a former world number one, whose own  grand slam ambitions were never fulfilled.

Victoria Azarenka, one of the three plotting a coup against  Wozniacki, kept up the heat with a comfortable 6-2 6-4 victory  over Germany’s Mona Barthel.

The Belarusian powerhouse nearly lost her composure when she  ran out of challenges and was unable to appeal a couple of close  line calls on match-point.

She composed herself to close it out on the attempt and  after tossing a ball away with disdain, was still fuming with  herself in a courtside interview.
