The 2026 Australian Open schedule begins Saturday night, with the first match starting at 7pm ET. Jannik Sinner has won back-to-back men’s singles titles and is the -115 favorite to defend his title again this year. Aryna Sabalenka lost to Madison Keys in the women’s singles final last year, but has appeared in three consecutive finals. She is a +200 favorite fending off other contenders such as Iga Swiatek (+600) and Elena Rybakina (+750).
Matches on the first day include Venus Williams vs. Olga Danilovic (3:00 a.m. ET) and Carlos Alcaraz vs. Adam Walton (4:30 a.m. ET). SportsLine expert Jose Onorato nailed down the best bets for both ties and highlighted two longshot bets.

Australian Open men’s best bets:
- Jannik Sinner (-115)
- Carlos Alcaraz (+180)
- Alex de Minaur (+7000)
Jannik Sinner (-115)
“Sinner emerges as a two-time defending champion in Melbourne, winning the title in both 2024 and 2025,” Onorato said. “His game is perfectly adapted to the fast hard courts of the Australian Open, where his combination of clean hitting, elite fitness and mental composure has made him almost untouchable for the past two seasons. He is currently improving in service and return games played on the hard outdoors. His win percentage against top-10 opponents on the surface is outstanding, and his tiebreak record highlights how well his game holds up in moments of pressure. When he’s fully healthy, there’s no better anchor at the top of the board. ”

Carlos Alcaraz (+180)
“Alcaraz is yet to win in Melbourne, but he has already won Grand Slam titles on every other surface and remains one of the most complete threats in the game,” Onorato said. “His performance on hard courts remains elite, with a win rate of over 75 percent over the past two years and one of the highest percentages of return points on second serves of any player. He has defeated nearly every top seed in both best-of-three and best-of-five matches, and has the physicality and resilience to withstand the rigors of the back end of Slam tournaments. If someone is going to stop Sinner, this is the most logical challenger.”

Alex de Minaur (+7000)
“The home crowd will be behind him, but that’s not just the story. De Minaur put together a hard, quietly strong stretch outdoors, improving his serve and scoring more points early in his rallies,” Onorato said. “His physical conditioning is top-notch and he has started to step on court and take control when he has time. He has had some quality wins against top-10 players in recent months and his rally tolerance and court speed make him well-suited for long matches in Australia’s brutal heat. If he gets a draw, he could be an unexpected name in the semi-finals.”

Australian Open women’s best bets:
- Arina Sabalenka (+200)
- Iga Świętek (+600)
- Mila Andreeva (+1700)
Arina Sabalenka (+200)
“Sabarenka has turned Melbourne into her stage. She has won multiple Australian Open titles and reached the final three years in a row,” Onorato said. “Her power game thrives in fast conditions, and her ability to win short rallies makes her perfectly suited to this surface. Statistically, she ranks near the top of the WTA in first serve points gained, ace rate, and short rally points (0-4 shots). If her serve is good, very few women will be able to stay with her for three sets. She should be considered a top contender again in 2026.”

Iga Świętek (+600)
“Although Światek has yet to lift a trophy in Australia, she remains one of the most reliable all-surface performers in the WTA. Her return game is unparalleled, consistently ranking in the top two or three for winning return games. She also has a tendency to dismiss lower-ranked opponents in straight sets, which helps her manage the physical demands over two weeks,” Onorato said. “She doesn’t seem as comfortable on hard as she is on clay, but she still performs well on surfaces. If her serve holds up, she’s as dangerous as Sabalenka in the Grand Slams.”

Mila Andreeva (+1700)
“Andreeva is just 18 years old, has already been to a Grand Slam semifinal, and has the tactical maturity of a veteran. Her ability to change pace, absorb power and build points gives her a real shot on the hard courts,” Onorato said. “She has wins over multiple top-10 players, and her game holds up under pressure. Her return positioning and ability to change pace will be especially tough in fast conditions. If she can handle the early rounds cleanly, her all-court game could carry her into Week 2 again.”
