The French Open stands apart from every other tennis major for one fundamental reason: clay. The slow, high-bouncing surface at Roland Garros extends rallies, rewards endurance, and historically narrows the field of legitimate contenders more than any other Grand Slam. For bettors, this creates a fascinating dynamic — the clay-court season offers a relatively predictable hierarchy of specialists, which books price accordingly. Market depth is strong across match winners, set betting, game totals, and handicap lines, but the real edges tend to emerge in early rounds where lesser-known clay-court grinders — players ranked outside the top 50 who've built their careers on dirt — face opponents with inflated reputations from hard-court results. The best-of-five-set format also suppresses upsets compared to ATP 250 and 500 events, making favorite-heavy strategies more viable but also compressing the odds.

Vig on French Open matches tends to be tighter than on lower-tier ATP events, simply because of the volume of betting action the tournament attracts. Sportsbooks compete aggressively on marquee matches — semifinals, quarterfinals, and any match involving top-ten players — often pushing margins below 3%. Early-round matches featuring qualifiers or players outside the top 100 typically carry wider margins, sometimes exceeding 5-6%, because books face greater uncertainty and lower liquidity. Comparing vig across books during the tournament's first week can uncover meaningful savings, particularly on those under-the-radar matchups.

The clay-court season builds from late March through June, and odds tend to sharpen as the French Open approaches because results from Monte Carlo, Barcelona, Madrid, and Rome give books — and bettors — a clearer picture of current form. Surface-specific form is arguably the single most important handicapping factor at Roland Garros. Weather matters too: rain delays disrupt momentum and can flip a match's trajectory, while heavy, humid conditions slow the court further, amplifying the advantage of defensive baseliners. Physical condition is critical in a best-of-five format on the sport's most grueling surface, making recent workload and injury history essential variables to track.

Frequently Asked Questions

What are the best ATP French Open lines today?

The table below shows which sportsbook has the best available price on each side of every upcoming ATP French Open event. Line shopping across multiple books can save you 1–3% per bet compared to sticking with a single sportsbook.

What is vig (vigorish) in sports betting?

Vig — short for vigorish, also called juice or overround — is the margin a sportsbook builds into its odds. It's the difference between the true probability of an outcome and what the odds imply. Lower vig means you keep more of your winnings on every bet. For example, a standard -110/-110 line has about 4.76% vig.

How often is this data updated?

We pull fresh odds from The Odds API three times per day — at 6:00 AM, 2:00 PM, and 10:00 PM UTC. Each snapshot captures the latest lines from every sportsbook that has posted odds. The timestamp at the top of the page shows the most recent refresh.

How is the vig grade calculated?

Each sportsbook is graded on a letter scale based on average vig: A+ (under 2%) is exceptional, A (2–3%) is excellent, B+ (3–4%) is above average, B (4–5%) is the industry standard, C (5–6%) is below average, and D (above 6%) indicates high-juice markets.

Why does lower vig matter for bettors?

Lower vig directly impacts your long-term returns. A bettor placing $1,000 per week at a book with 4% vig loses roughly $40/week to the house edge. At 2% vig, that drops to $20/week — a $1,040 difference over a year. For serious bettors, shopping for lower vig is one of the most reliable ways to improve profitability.

What sportsbooks do you track?

We track both regulated US sportsbooks (DraftKings, FanDuel, BetMGM, Caesars) and offshore books (Bovada, BetOnline, MyBookie, BetUS, LowVig.ag, BetAnySports). Data comes from The Odds API, which aggregates real-time lines from licensed sources.

How We Calculate These Numbers

Data Source
All odds on this page come from The Odds API, which aggregates real-time lines from licensed US and offshore sportsbooks. We track moneyline, spread, and totals markets across every sport with active betting lines.
Update Frequency
We pull a fresh snapshot of every tracked market three times per day — at 6:00 AM, 2:00 PM, and 10:00 PM UTC. Each snapshot captures the latest lines from every sportsbook that has posted odds for a given event. The timestamp at the top of each page tells you exactly when the data was last refreshed.
Vig Calculation
Vig (short for vigorish, also called juice or overround) measures the margin a sportsbook builds into its odds. We calculate it by converting the odds on each side of a market to implied probabilities, summing those probabilities, and subtracting 100%. For example, a market priced at -110/-110 implies 52.38% on each side — a total of 104.76%, meaning a vig of 4.76%. Lower vig means better value for bettors because you keep more of your winnings.
Per-Market Breakdown
We compute vig separately for each market type: moneyline (h2h), point spreads, and totals (over/under). The "average vig" shown for each sportsbook is the mean across all market types weighted by the number of events sampled in each market.
Grading Scale
Every sportsbook receives a letter grade based on its average vig: A+ (under 2%) is exchange-level pricing. A (2–3%) is very competitive. B+ (3–4%) is above average. B (4–5%) is the industry standard — a -110/-110 line is 4.76%. C+ (5–6%) is slightly below average. C (6–7%) is below average. D (7–8%) is high vig. D− (8–10%) is very high vig. F (10%+) is predatory pricing. See the full Vig Index Methodology for formulas, worked examples, and known limitations.
Trend Tracking
We store daily snapshots for 30 days, allowing us to show 24-hour and 7-day vig trends. A downward trend (improving) means sportsbooks are tightening their lines — often in response to increased competition or higher betting volume as a season heats up.
