ATP Miami Open moneyline betting represents the purest form of tennis wagering, requiring bettors to simply pick the match winner without any point spreads or handicaps. Unlike team sports where point differentials matter, tennis moneylines focus exclusively on who advances to the next round, making them particularly straightforward for the Miami Open's knockout format. The hard court surface at this Masters 1000 event tends to favor powerful servers and aggressive baseliners, which can create predictable patterns that sharp bettors exploit through moneyline positions.
Moneyline value emerges most clearly when public perception diverges from actual match dynamics, particularly with aging stars facing younger opponents or when recent form contradicts ranking positions. Early-round matches featuring unseeded players often present the strongest opportunities, as oddsmakers rely heavily on ATP rankings that may not reflect current hard court form. The vig on ATP moneylines typically runs 4-6% at most books, making them more favorable than prop markets or set betting, which can carry 8-10% juice. Experienced tennis bettors focus on moneylines during the first week when the field is deepest, as later rounds between elite players often feature efficient pricing that leaves little room for advantage.

Frequently Asked Questions
Which sportsbook has the lowest ATP Miami Open moneyline vig?
Pinnacle currently has the lowest vig at 0.63%, earning a grade of A+.
What is the Miami Open?
The Miami Open is an ATP Masters 1000 and WTA 1000 tennis tournament held annually in March-April at Hard Rock Stadium in Miami Gardens, Florida. Along with Indian Wells, it forms the "Sunshine Double" — two of the biggest tennis events outside the Grand Slams.
How does Miami Open vig compare to Grand Slams?
Miami Open vig is generally slightly higher than Grand Slam vig because the tournament attracts less overall betting volume. However, matches featuring top-10 players still see competitive pricing at sharp sportsbooks.
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.
