The five-time major victor will next play No. 14-seeded Anastasija Sevastova, who beat her at the U.S. Open past year in her return to a Grand Slam to tournament.
"I can't thank him enough for all the things but today he is not here". Also, it's the first time since 1997 that the Australian Open will not feature either of the Williams sisters in the second round after Serena withdrew from the tournament at the start of the month following her pregnancy. "I played flawless tennis, like I never stopped".
"What a comeback it was, and it was definitely the highlight of the year".
Sixteen-time Grand Slam champion Nadal insists he is feeling fine despite struggling with a knee injury and ready to go deep at an event that he has only won once - in 2009 - among his string of major triumphs.
Djokovic, with his 12 Grand Slam titles, his record-tying six Australian Open titles and his 223 weeks at No. 1 (fifth-most in the game's history), has spent 18 months as a mystery.
Nadal skipped the year-end championship last November and delayed the start of his 2018 season, so he's also had only exhibition matches to see how his right knee has recovered.
Rafael Nadal says he has no doubts over a knee injury as he destroyed his opening round opponent at the Australian Open on Monday. "So that's the good news".
On the men's side, Novak Djokovic and Stan Wawrinka are back from injury, but Andy Murray and Kei Nishikori remain out.
"It's been a couple of years and I wanted it to be really meaningful to me".
"After the injury and the tough times it's really an awesome feeling".
"I learned what it feels like to be on the ground and seeing life from the ground, and I'm not shying away from any part of that", she said. Five-time Australian Open champion Federer was 35 years old when he went all the way at Melbourne Park last year. World No.3 Dimitrov needed one hour and 38 minutes to prevail over the player 220 spots lower than him on the ATP rankings in their first-ever meeting.
"There were definitely a lot of wins this year", she said at season's end in Singapore, "and definitely a lot of wins that were satisfying". She could face two-time Wimbledon champion Petra Kvitova in the third round and Karolina Pliskova in the quarters. "But I feel good", said the 31-year-old, who played his first Australian Open in 2004.
Muguruza is expecting the constant changes at the top of the women's game to continue in 2018. "This is going to be a very interesting year".
The top-ranked Spaniard, who made a splash as a teenager with his trademark sleeveless shirts and knee-length pirate trousers, came into this year's Australian Open with questions about his health and readiness to compete following a taxing season that saw him capture two Grand Slams and return to No. 1.
Djokovic, a surprise second-round loser here a year ago, is hoping he can get fit enough to change that in 2018.
Where can I watch the live streaming of the matches? It would bring so many returns from so many absences that it seemed primed to take a sport with holes in its draws and stitch the whole thing back together.
