Frequently Asked Questions
Which sportsbook has the lowest vig for MLB?
LowVig.ag currently has the lowest average vig for MLB at 2.97%, earning a grade of A.
How do sportsbook odds compare for MLB?
We compare 20 sportsbooks for MLB. The vig ranges from 2.97% (LowVig.ag) to 6.46% (BetRivers).
When do small vig differences matter for MLB?
The top two books (LowVig.ag and Pinnacle) are separated by just 0.06%. While small, this adds up over volume — a bettor placing $1,000/week saves roughly $1 per week by choosing the lower-vig book.
Is MLB vig getting better or worse?
MLB vig is currently worsening (increasing). Average vig has shifted by 0.25 percentage points since yesterday. We track these changes daily to help bettors identify the best windows for placing wagers.
Why does MLB have unique vig patterns?
MLB betting revolves around the moneyline rather than point spreads (though run lines exist). This means vig varies significantly based on the matchup — a game between evenly matched teams will have much tighter vig than a heavy favorite vs underdog scenario.
When is MLB season?
MLB runs from late March through October, with the World Series typically ending in late October or early November. Spring training games begin in February but rarely appear on most sportsbooks. The long 162-game season means consistent odds availability for six months.
Which MLB market type offers the best value?
For MLB, moneylines on close matchups (both teams near even) tend to have the best vig. Run line (±1.5) vig is typically higher because it's a less liquid market. Totals vary based on the game but are generally competitive at sharp books.
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.
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.
