Four-time Australian Open champion, Roger Federer is through to the third-round after holding off the challenge of American prospect Noah Rubin.
The 35year-old Swiss maestro, who is seeded 17th after missing the second half of the 2016 season with a knee injury, saved two set points in the third to win 7-5 6-3 7-6 (7-3).
He is looking forward to be the second oldest male winner of a grand slam in the Open era. After winning the 20year-old Noah, he attributed the win to experience.
"I have played out here many, many times, that's my advantage maybe," he said, after claiming victory in two hours four minutes.
"If I could have signed (a contract) to be in the third round, feeling this way, weeks or days or a month ago, I would have taken it.
"I'm still hoping to feel better and better and better as we go along."
The 17-time grand slam winner will now play 2010 Wimbledon finalist Tomas Berdych next. He had defeated the Czech star in the quarterfinal stage last year.
