A ruthless Rafa Nadal preserved his creaky knees for tougher tests down the road by routing Dominican journeyman Victor Estrella Burgos 6-1 6-1 6-1 to sail into the second round of the Australian Open on Monday.

Playing his first competitive match since pulling out of the ATP Tour Finals with knee trouble in November, the world number one showed no signs of early season rust as he tore through the evening match at Rod Laver Arena in one hour and 34 minutes.

The 31-year-old, who lost last year's final in a five-set classic with long-time rival Roger Federer, brought up three match points with a huge serve and closed out the match on the first when 37-year-old Estrella Burgos parried a return long.

Nadal's bid for a second Australian Open title and 17th grand slam championship will continue against Argentine Leonardo Mayer.

India's Yuki Bhambri bows out

Top-ranked Indian men's singles player Yuki Bhambri bowed out of the tournament as early as in the first round after losing to former finalist Marcos Baghdatis in straight sets.

After running the veteran campaigner close in the first set, which went to the tie-breaker, Bhambri went downhill with an erratic display of tennis to lose the match 6-7, 4-6, 3-6.

Notably, Bhambri has not gone past the first round at the season's first Grand Slam as he has exited the tournament similarly in 2015 and 2016.

Grigor Dimitrov schools Austrian Novak

Grigor Dimitrov looked every inch the potential grand slam champion as he schooled qualifier Dennis Novak 6-3 6-2 6-1 to reach the second round.
