The women’s tennis grand slam season begins on Sunday when the 2025 Australian Open kicks off at Melbourne Park. Two-time defending champion Aryna Sabalenka has won the last three hard-court grand slams, and she is the +220 favorite (risk $100 to win $220) in the 2025 Australian Open odds. Sabalenka sits atop the WTA singles rankings, but Iga Swiatek is right on her heels. Swiatek is a five-time grand slam champion, and she is +600 to win the first grand slam of the year on the tennis odds board.
American Coco Gauff continues to seek her second major title, and she is listed at +400 in the tennis betting odds. Which players offer the most value when it comes to 2025 Australian Open women’s bets? Before making any 2025 Australian Open picks for the women’s singles tournament, you need to see who proven SportsLine tennis handicapper Jose Onorato is backing.
Onorato grew up playing competitive tennis in Caracas, Venezuela. After coming to the U.S., he trained with famed coach Nick Bollettieri at IMG Academy in Florida and faced players like Robert Farah, now one of the world’s top-ranked doubles players.
Onorato, who holds dual degrees in finance and economics from the University of Miami, does extensive research before placing any tennis betting picks. He studies current form, players’ tendencies on a particular surface, weather conditions and many other relevant factors. That systematic approach has helped Onorato go 168-106-8 (+107.12 units) at sportsbooks and on betting apps since 2022. In the 2024 men’s US Open, he included Jannik Sinner (+320) in his best bets.
Now, Onorato has scrutinized the latest Australian Open 2025 women’s odds and released his coveted best bets to win it all. He’s sharing all of his picks and analysis at SportsLine.
Top 2025 Australian Open women’s predictions
Onorato is fading Swiatek, even though she is a five-time grand slam champion. Swiatek won a hard-court slam at the 2022 US Open, but she has failed to win a major title outside of clay since then. She has only advanced to the Australian Open semifinals once in her career (2022), getting bounced in the fourth round in 2023 and the third round in 2024.
Swiatek has not had much more success than that at the US Open in the other hard-court slam in recent years, making a fourth-round appearance in 2023 and the quarterfinals last year. Sabalenka has proven to be significantly better than Swiatek on this surface, and players like Gauff have also proven to be tough outs. Onorato knows that Swiatek remains one of the best players in the sport, but he does not see any value at this price. See who else to back and fade here.
