First serve at Rod Laver Arena is scheduled for 3:30 a.m. ET. Sabalenka is the -225 favorite (risk $225 to win $100) in the latest Sabalenka vs. Gauff odds, while Gauff is a +175 underdog. The over/under for total games in the match is 21.5, with Sabalenka favored by 3.5 games. 

Before you make any Gauff vs. Sabalenka picks or 2024 Australian Open predictions, you NEED to see what tennis expert Jose Onorato has to say.

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 bets. He studies current form, players' tendencies on a particular surface, weather conditions and many other relevant factors. That systematic approach has helped Onorato go 128-90-7 -- up 69.25 units -- since 2022!

The expert knows Sabalenka cruised past 2021 French Open champion Barbora Krejcikova 6-2, 6-3 to become just the second woman (Chris Evert) to win the first eight Grand Slam quarterfinal matches of her career. The 25-year-old Belarusian also joined Jennifer Capriati and Serena Williams as the only women this century to reach the semifinals in six consecutive major tournaments. Since being upset by 2020 Australian Open champ Sofia Kenin in the first round at Wimbledon last year, Gauff has won 12 straight Grand Slam matches. The 19-year-old American began this event with four straight-set victories before outlasting Marta Kostyuk 7-6 (8-6), 6-7 (3-7), 6-2 in the quarterfinals.
