In sports betting, odds reflect more than numbers. They capture momentum, confidence, and public perception. TonyBet Ontario is one of the most active sportsbooks for tennis. And the most recent odds reveal which athletes are considered frontrunners in 2025. From the men’s tour to the women’s draw, a few names stand out as clear betting favorites.
Jannik Sinner: The Rising King of Men’s Tennis
TonyBet currently lists Jannik Sinner as the outright favorite to win the 2025 US Open. His odds have hovered close to +110, a rare figure that signals high confidence from bookmakers and bettors alike. This surge in favoritism follows Sinner’s victories at the Australian Open and Wimbledon earlier this year.
Sinner’s consistency, his powerful baseline game, and his ability to dominate on hard courts make him a natural pick. TonyBet’s lines also reflect how often he has converted his seeding into deep tournament runs. While challengers like Carlos Alcaraz remain close behind in odds, Sinner’s recent form puts him firmly at the top.
Aryna Sabalenka: Defending Champion and Market Leader
On the women’s side, Aryna Sabalenka is commanding the odds. As the defending US Open champion, she enters the tournament with both momentum and a proven track record on hard courts. TonyBet has priced her as one of the strongest contenders, consistently ahead of most of the field.
Sabalenka’s aggressive style, booming serve, and resilience in pressure moments align with the qualities bettors trust. Her dominance in Grand Slam play over the past two years adds extra weight to her position as the market leader. For those tracking TonyBet’s odds, she is the most bankable pick among the women.
Iga Świątek: Close Behind the Favorite
While Sabalenka holds the slight edge, Iga Świątek is not far behind. The Polish star, renowned for her clay-court brilliance, has increasingly proven herself on hard surfaces. TonyBet’s odds place her as the second most likely to lift the trophy, highlighting her adaptability and rising confidence outside Roland Garros.
Świątek’s consistent ranking at the top of the WTA, combined with her mental strength in long matches, makes her a reliable option for bettors. Even when not the favorite, her odds remain short — signaling just how respected she is in the betting markets.
Why the Odds Favor Them
Several factors explain why these three athletes dominate TonyBet’s odds:
- Recent Results: Both Sinner and Sabalenka have secured Grand Slam titles in 2025, cementing their reputations.
- Seeding Advantages: Top players often face easier early-round opponents, improving their chances of deep runs.
- Public Sentiment: Bettors gravitate toward recognizable names, and sportsbooks adjust lines accordingly.
- Surface Fit: Hard courts, especially at the US Open, suit aggressive baseliners like Sinner and Sabalenka.
