Defending champion Rafael Nadal overcame a spirited challenge from Australia's Peter Luczak to move into the second round of Australian Open on Monday.
The world No. 2 appeared sluggish in the opening stages of the match and was forced onto the back foot by Luczak's powerful ground strokes, but settled and ultimately prevailed 7-6 (0), 6-1 and 6-4.
The Spaniard said he was prepared for a tough battle against the Australian No. 2.
"Playing the first round of one Grand Slam, you know, always the first round is a little bit more nervous and you have to start. First rounds are always difficult to play very well," he said.
The second seed will meet the winner of the match between Slovakian Lukas Lacko and Argentina's Leonardo Mayer in the next round.
