Canadians at the Australian Open: Players, Odds and History

The Australian Open – the first Grand Slam of the 2025 tennis season – gets underway in Melbourne on Monday and there are a number of Canadian players making the trip Down Under.

Only one Canadian has ever won a Grand Slam title, with Bianca Andreescu landing the 2019 US Open when she was just 19 years old, toppling Serena Williams in the final. 

The injured-plagued Andreescu is unable to play at Melbourne Park, leaving Felix Auger-Aliassime, Denis Shapovalov, Gabriel Diallo, Leylah Fernandez and Rebecca Marino to pick up the slack.

Fernandez is a former Grand Slam finalist (2021 US Open), while Auger-Aliassime (2021 US Open) and Shapovalov (2021 Wimbledon) are former Slam semifinalists. 

Auger-Aliassime and Shapovalov also advanced to the Australian Open quarterfinals in 2022, where the former had a match point to reach the semis before falling to Daniil Medvedev.

Let’s break down the chances of the Canadians who earned direct entry into the Australian Open main draw and their odds to win.

Canadians in Men's Singles

Felix Auger-Aliassime (+6600)

Based on both past results and sheer talent, Auger-Aliassime represents Canada’s best chance to put another Grand Slam title on the board.

The 24-year-old has peaked as high as No. 6 in the rankings and has reached at least the quarterfinals at three of the four majors.

Auger-Aliassime's Aussie Open history is solid but unspectacular. In addition to his quarterfinal run three years ago, he has advanced to the fourth round twice (2021 and 2023). However, he lost in the first round in 2020 and in the third round last season.

With 32 players seeded in both the men’s and women’s brackets, Auger-Aliassime takes the 29th position and will begin his quest for glory against German Jan-Lennard Struff.

Denis Shapovalov (+10000) 

Shapovalov’s high-risk, high-reward style of play naturally leads to wildly inconsistent results. It also doesn’t help that injuries have largely prevented him from putting together any sustained stretches of success in recent seasons. 

Although still a long way off from his career-high ranking of No. 10, Shapovalov is heading into 2025 trending in the right direction.

After falling as low as 140th this past July, the left-hander is currently No. 58. Late-season results in 2024 included a title in Belgrade and a quarterfinal performance in Basel.

Shapovalov has never done much in Melbourne aside from his 2022 quarterfinal finish, losing three times in the third round, once in the second round and twice in the first round.

He has been drawn against Spaniard Roberto Bautista Agut in round one.

Gabriel Diallo (N/A) 

A former college standout at the University of Kentucky, Diallo announced himself on the professional scene in 2024. He started the season at No. 139 in the rankings and concluded it at No. 87.

Highlights included a third-round effort at the U.S. Open and a runner-up showing in Almaty.

Diallo played in each of the first two weeks of this new tennis season and results were mixed. He advanced to the Hong Kong second round as a qualifier but lost his opening match in Auckland to Lorenzo Sonego in a third-set tiebreaker.

This marks Diallo’s third trip to the Australian Open and his first time in the main draw, where he will play Italian Luca Nardi.

Canadians in Women's Singles

Leylah Fernandez (+6600) 

With Andreescu largely off the tour these days, Fernandez is by far the most well-known Canadian player in the women’s game.

Although unable to maintain the heights she reached at the 2021 US Open, a mostly productive 2024 campaign has the lefty positioned nicely at 31st in the rankings and she will be the 30th seed at the Australian Open.

Fernandez wrapped up this past season in stellar form, winning multiple matches at every one of her last three tournaments. The 22-year-old also finished runner-up on the grass courts of Eastbourne and reached the quarterfinals in Doha and Cincinnati. 

Success in Melbourne has so far eluded her. In five appearances, she has lost in the opening round three times and in the second round twice.

Fernandez has been drawn against Yuliia Starodubtseva in round one.

Rebecca Marino (N/A)

Currently ranked 102nd in the world, Marino was initially scheduled to participate in the qualifying rounds. However, she snagged a late spot in the main draw when Karolina Pliskova withdrew from the tournament.

At 34-years-old, Marino has won eight matches all time at the four Grand Slams (two in Australia). The Toronto native’s career-high ranking is No. 38, which she achieved in 2011.

Marino has been drawn against British number one Katie Boulter, the 22nd seed, in the opening round.
