Rafael Nadal opened his Australian Open campaign with a 6-2 6-3 6-0 victory over Bolivia's Hugo Dellien.
It was tougher than the scoreline appeared, with Dellien - the first Bolivian to play at the tournament - keeping the world number one out on court for more than two hours.
But there were no alarms for Nadal, who said: "For me personally it has been a very positive start. What you want is to win in the first round and, if you can do it in straight sets, even better."
If Nadal wins in Melbourne, it will be a record-equalling 20th grand slam title.
But the Spaniard said that he is not dwelling on the prospect of matching Roger Federer's current record.
"I think about Sousa or Delbonis. That's all. I think about my practice of tomorrow, try to follow up the level of tennis that I played in the third set," he said.
"If I am able to reach my highest level, that's the thing that I have to worry about. If I am able to play at my highest level, normally I am able to produce some good chances. If not, impossible.
"So I don't care about 20 or 15 or 16. I just care about trying to keep going, keep enjoying my tennis career.
"If I reach 20, fantastic. If I reach 21, better. If I reach 19, super happy about all the things that I did in my tennis career."
