With the 2023 French Open beginning at 5 a.m. ET on Sunday, Spain's Carlos Alcaraz enters as the favorite at Roland Garros in Paris. He is the top-ranked player in the world, and is vying for his second Grand Slam victory after securing the win at the 2022 U.S. Open. But another run to a title won't be easy, thanks to a hard-hitting field. Expected to challenge Alcaraz for the championship are a number of contenders, including second-ranked Daniil Medvedev, third-ranked Novak Djokovic and sixth-ranked Holger Rune.

Alcaraz is at +150 in the latest 2023 French Open odds to win the grand slam title at Caesar's Sportsbook. Djokovic follows at +230, with Rune at +700. Other notables have Medvedev at +800, Jannik Sinner of Italy at +1100, Stefanos Tsitsipas of Greece at +1100 and Casper Ruud of Norway at +1600. Before making any men's 2023 French Open picks, you need to see who SportsLine tennis expert Jose Onorato is backing.

Onorato grew up playing competitive tennis in Caracas, Venezuela. After coming to the United States, 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, a player's tendencies on a particular surface, weather conditions and many other relevant factors. That systematic approach helped Onorato go 96-67-7 -- up 60.42 units -- in 2022.

Earlier this year, he correctly predicted Aryna Sabalenka (-140) to win the Australian Open women's final over Elena Rybakina and to do so two sets to one (+325).

Now, Onorato has broken down the latest odds for the men's draw of the 2023 French Open and released his coveted best bets to win it all. He's sharing all of his picks and analysis at SportsLine.

Top 2023 French Open men's predictions

One surprise: Onorato isn't backing Djokovic. Although Djokovic is formidable and is coming off winning the Australian Open singles title, Onorato sees value elsewhere. Although the 36-year-old has won the last two Grand Slam events he has participated in, a lingering elbow issue could prove to be damaging to his chances. In all, Djokovic has won 22 Grand Slam events since he turned pro in 2003.

Among the challengers standing in his way include Rune. The 20-year-old from Denmark already has four career titles, and reached the quarterfinals of last year's French Open, where he lost to Casper Ruud 6-1, 4-6, 7-6 (2), 6-3. Rune is coming off a second-place finish at last week's Rome Open, where he fell to Medvedev 7-5, 7-5.

The 24-year-old Tsitsipas is also in good position to win his first Grand Slam event. Since turning pro in 2016, he has continued his improvement, reaching the finals of the French Open in 2021 and the finals of the 2023 Australian Open. He has nine career titles and has compiled a 276-127 (68.5%) record in singles play. You can see all of Onorato's picks here.
