Pinnacle leads with 2.75% vig (A), followed by BetMGM at 3.33%. The spread between #1 and #17 is 5.60% — book choice matters significantly for ATP Italian Open.
The ATP Italian Open, held annually at the Foro Italico in Rome, occupies a critical spot on the tennis calendar as one of the most prestigious Masters 1000 events and the final major clay-court tune-up before Roland Garros. For bettors, this tournament offers a rich market landscape. Clay-court tennis produces distinct scoring patterns — longer rallies, more breaks of serve, and matches that frequently extend to three sets — which creates valuable opportunities in both match-winner and totals markets. The 96-player draw ensures a full week of action with deep market availability, from outright winner and set betting to game handicaps and in-play markets that shift dramatically with each break of serve.
Vig on ATP Italian Open markets tends to vary significantly by round and matchup profile. Early-round matches featuring lower-ranked qualifiers often carry wider margins, sometimes exceeding 6-8%, as sportsbooks price in greater uncertainty and expect lower handle. By the quarterfinals and beyond, when household names like Djokovic, Sinner, or Alcaraz are involved, margins compress noticeably — often to 3-5% on match-winner lines — as books compete aggressively for volume on high-profile contests. Prop and set-betting markets generally carry wider vig throughout the tournament, so sharp bettors tend to find the best value on head-to-head lines in later rounds.
Seasonal context matters enormously when betting Rome. The tournament typically falls in mid-May, meaning players are several weeks into the European clay swing after Monte Carlo and Madrid. Form lines from those preceding events are highly predictive, but fatigue and minor injuries accumulated through the swing can dramatically shift value. Rome's outdoor setting also makes weather a factor — afternoon heat favors heavy topspin players, while cooler or damp conditions can neutralize clay-court specialists. Home-crowd energy is another real variable; Italian players like Sinner and Musetti consistently outperform their rankings in Rome, and books sometimes underadjust for that dynamic, particularly in early rounds.

Frequently Asked Questions
Which sportsbook has the lowest vig for ATP Italian Open?
Pinnacle currently has the lowest average vig for ATP Italian Open at 2.75%, earning a grade of A.
How do sportsbook odds compare for ATP Italian Open?
We compare 17 sportsbooks for ATP Italian Open. The vig ranges from 2.75% (Pinnacle) to 8.35% (ReBet).
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.
