Pinnacle leads with 0.63% vig (A+), followed by DraftKings at 1.53%. The spread between #1 and #9 is 6.96% — book choice matters significantly for ATP Miami Open.
The ATP Miami Open, held annually at Hard Rock Stadium in Miami Gardens, is one of the premier Masters 1000 events on the tennis calendar and offers a deep, liquid betting market. Tennis betting in general rewards sharp analysis because of the sport's individual nature — there are no teammates to mask weaknesses, and matchup dynamics between specific playing styles can override raw rankings. The Miami Open's hard-court surface tends to favor big servers and aggressive baseliners, and the humid South Florida conditions can dramatically affect player stamina and ball behavior. With a 96-player main draw and multiple rounds of play over nearly two weeks, the tournament generates hundreds of individual match markets, plus a wide range of props including set betting, total games, and outright winner futures.
Vig on ATP Miami Open matches varies significantly depending on the round and profile of the match. Early-round contests featuring heavy favorites against qualifiers or lower-ranked players tend to carry wider margins, as sportsbooks have less incentive to sharpen lines on lopsided matchups that attract limited two-way action. As the tournament progresses into the quarterfinals and beyond, margins tighten considerably — these are the matches that draw the heaviest handle and the most attention from sharp bettors, forcing books to compete on price. Comparing vig across sportsbooks becomes especially valuable in these later rounds, where even small differences in juice can meaningfully impact long-term profitability.
The Miami Open typically runs in late March, immediately following the Indian Wells Masters, and this back-to-back scheduling is a critical factor for bettors. Player fatigue, nagging injuries from the preceding tournament, and the adjustment from the desert climate to coastal humidity all create exploitable edges. Bettors should monitor withdrawal lists and practice reports closely, as late scratches are common. Surface form from the North American hard-court swing matters more than overall ranking, and players who thrive in heat and humidity — historically, athletes like Novak Djokovic and Carlos Alcaraz — tend to outperform their odds. The concentration of high-profile matches in the second week also creates peak periods where line shopping across books yields the most value.

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.
