AUSSIES HIGHLIGHT BIG DAY AT MELBOURNE PARK

There are plenty of reasons — 12 specifically — to tune into Monday’s action at Melbourne Park, with a dozen Australians looking to progress in the tournament.

First up, Ajla Tomljanović is one of a number of wildcards playing on Day 2, with the Wimbledon and US open quarter-finalist taking on Ashlyn Krueger at 11.30am on Margaret Court Arena.

Funnily enough, it is the second time the pair have played this month, with the American winning in straight sets at the Adelaide International last Saturday.

Jordan Thompson will also be in action on Margaret Court Arena against German qualifier Dominik Koepfer, while there will be a pair of Australians playing on Court 3 from 11am.

Up first is 20-year-old wildcard Talia Gibson, who faces Turkey’s Zeynep Sonmez before James Duckworth comes up against Switzerland’s Dominic Stricker.

Elsewhere, two other Australian wildcards will also feature early in the day with James McCabe playing qualifier Martin Landaluce while Perth’s Tristan Schoolkate faces Taro Daniel.

Aleks Vukic is also in action against Damir Dzumhur on Court 13, with that match expected not before 2.30pm.

DAY 1 WRAP: Big name avoids disaster as fan favourite pulls off epic comeback

NIGHT 1 WRAP: All the results and highlights from the first night of action

There are several big name Australians featured in the later session too, with rising star Maya Joint looking to capitalise on her recent run of form. But she will be up against it, facing American seventh seed Jessica Pegula on John Cain Arena from 5pm.

Nick Kyrgios will follow her in his return to Melbourne Park against Jacob Fearnley.

Kyrgios’ good friend Thanasi Kokkinakis is also in action despite entering the tournament under an injury cloud, facing Roman Safiullin in Kia Arena, while soon after Christopher O’Connell has a tough challenge awaiting him in 12th seed Tommy Paul.

RED-HOT US STAR THE BIG THREAT TO REIGNING WOMEN’S CHAMP

First up on Rod Laver Arena is a red-hot Coco Gauff, who said on Friday that keeping cool in tough moments was behind a scintillating run of form that has made her a major threat to Aryna Sabalenka at the Australian Open.

Sabalenka is the world number one and favourite to win a third title in a row in Melbourne.

But the 20-year-old Gauff, ranked three, finished 2024 with a flourish by winning the China Open and the season-ending WTA Tour Finals.

She took that form into this season, winning all her singles matches at the United Cup including beating world number two Iga Swiatek in straight sets to lead the United States to glory.

Gauff faces a potential banana skin against the 2020 Australian Open champion and fellow American Sofia Kenin in the first round.

WORLD NO.1 LOOKING TO PUT DOPING SCANDAL BEHIND HIM

Later on Rod Laver, Jannik Sinner will try to put a doping scandal behind him when he kicks off his Australian Open defence against Nicolas Jarry.

Italian world number one Sinner is hot favourite after a breakthrough 2024 built on the back of his come-from-behind victory over Daniil Medvedev in last year’s final.

It was his maiden Slam crown and he went on to add the US Open, with his overwhelming dominance illustrated by being more than 4,000 ranking points clear of world number two Alexander Zverev.

He has played Chile’s Jarry twice before, winning their last clash in Beijing in September. But he needed to rally from a set down.

Should he get past Jarry, the top seed could meet Greece’s Stefanos Tsitsipas or Australian Alex de Minaur in the quarter-finals.
