Women’s top seed Simona Halep of Romania faces Australian wildcard Destanee Aiava in the first round, with second seed Caroline Wozniacki starting out against Halep’s compatriot Mihaela Buzarnescu.
Serena Williams will not defend the women’s title having had her first child last year but 2008 champion Maria Sharapova, who failed a drugs test at the tournament in 2016, is back unseeded after a ban and will face Germany’s Tatjana Maria.
Williams’s sister Venus, who lost to her sibling in the final last year, is seeded fourth and the 37-year-old was handed a tricky first encounter against Swiss former world number seven Belinda Bencic, who is 17 years her junior.
Men’s third seed Grigor Dimitrov will face a qualifier, with Alexander Zverev, ranked fourth, playing Italian Thomas Fabbiano but with 2014 champion Stan Wawrinka, returning after surgery, in his section of the draw.
Young gun Zverev had little luck in his first Australian Open draw as a top five seed with either Wawrinka, who plays Ricardas Berankis, or Novak Djokovic potentially standing in his path in the quarter-finals.
Six-times Melbourne Park champion Djokovic, seeded 14th after missing the back end of last season with an elbow injury, will take on American lefthander Donald Young in his first match with mercurial Frenchman Gael Monfils looming in round two.
Federer also has Milos Raonic, Juan Martin del Potro, David Goffin and Tomas Berdych in his quarter of the draw, while Nadal would appear to have the easier section, although former U.S. Open champion Marin Cilic looms as a last-eight opponent.
If the draw goes to seeding, Dimitrov would face American Jack Sock in the last eight, with ailing world number five Dominic Thiem, who withdrew from Kooyong because of illness on Thursday, taking on Zverev.
Britain’s Andy Murray and Japan’s Kei Nishikori have already withdrawn from the championships and women’s world number three Garbine Muguruza has twice pulled out of tournaments over the last two weeks due to leg cramps and a thigh problem.
The Wimbledon champion is scheduled take on France’s Jessika Ponchet in the first round, while French Open champion Jelena Ostapenko was paired with veteran Francesca Schiavone and U.S Open champion Sloane Stephens will take on China’s Zhang Shuai.
Australia’s sole men’s seed, Nick Kyrgios, takes on Brazilian Rogerio Dutra Silva and local women’s 18th seed Ashleigh Barty takes on Belarusian Aryna Sabalenka.
Australian Open rules to prevent first-round farce
Players could forfeit their prize money if they retire from first-round singles matches at the Australian Open, under new rules aimed at limiting the early injury withdrawals which have long caused controversy at Grand Slams.
Players will also be able to claim 50 percent of their prize money if they pull out before their first match, an incentive designed to allow a replacement to play instead.
With tens of thousands of dollars at stake just for playing in round one, early injury pull-outs have often caused suspicion at Grand Slams, particularly at last year’s Wimbledon.
Eight players retired from the first round at the All-England Club, including the opponents of Roger Federer and Novak Djokovic during the second sets of their matches on Centre Court.
“A player should not go on court if he knows he should not finish,” Federer said at the time, while Djokovic noted his
opponent, Martin Klizan, even “had issues walking onto court” with a calf injury.
Now, under new rules by the International Tennis Federation (ITF), any Grand Slam player who withdraws after 1200 local time yesterday before the tournament draw will still receive 50 percent of first round prize money.
Their replacement - a ‘lucky loser’ from the qualifying tournament - will get the other 50 percent of the first-round prize money. But players who do not “perform to the required professional standard” in round one, including by retiring, also risk being fined their prize money, the new rules say.
‘Couldn’t care less’
Australian bad boy Bernard Tomic was fined a third of his £35,000 ($47,500) prize money for unsportsmanlike conduct at Wimbledon, after saying he felt “bored” and “couldn’t care less” following a straight-sets defeat on day one.
Any repeat this year and he would lose the lot.
A similar controversy blew up at the Auckland Classic this week when four players pulled out before their opening matches, citing injury or illness.
Simply by turning up, they were eligible for prize money and avoided a fine. Chris Kermode, executive chairman of the men’s tour, the Association of Tennis Professionals (ATP), promised a shake-up, although he accepted the players’ reasons for withdrawing.
“Ranking points, player withdrawals and how we deal with that is something we’ve got to and are looking at,” he told Fairfax Media in Auckland.
In a separate rule change designed to get matches started more quickly, warm-up times will be strictly enforced.
Players will be fined up to US$20,000
for taking more than one minute after walking on court to get to the coin toss.
They will also be restricted to five minutes’ warm-up time on court, and another one minute before the first point.
However, plans for a shot clock to enforce a 25-second time limit between points have been shelved, and will only be used in the qualifying tournament at Melbourne Park. New rules reverting Grand Slams to 16 seeds from the current 32 are due to come into force in 2019.
