MLB presents one of the most analytically rich betting environments in professional sports. With a 162-game regular season running from late March through September, followed by an October postseason, the sheer volume of games creates deep, liquid markets across moneylines, run lines, totals, and an extensive array of player props. Unlike sports with frequent scoring fluctuations, baseball's run-scoring environment is relatively low and tightly distributed, meaning small edges in pricing carry outsized significance. The prevalence of the moneyline as the primary bet type — rather than a point spread — also makes MLB unique, as bettors must navigate implied probabilities directly rather than working around a fixed number.
Vigorish on MLB markets tends to be tighter than in many other sports, particularly on moneylines for games between evenly matched teams. Sportsbooks typically embed margins in the 2–5% range on standard moneylines, though this can widen considerably on heavy favorites, run lines, and derivative markets like first-five-inning bets. Because of the large daily slate — often 15 games — books are pricing hundreds of markets simultaneously, which can lead to softer lines, especially in the early morning when odds first post. Comparing vig across sportsbooks on a per-market basis is especially valuable in baseball, where even a cent or two of juice difference on a -150 favorite compounds meaningfully across a full season of wagering.
Several factors drive meaningful line movement in MLB. Starting pitching is the single most influential variable, and a late scratch can shift a moneyline by 30 cents or more. Weather conditions — particularly wind direction and humidity at outdoor parks — directly affect totals, and sharp bettors monitor ballpark-specific forecasts closely. Platoon splits (how hitters perform against left-handed versus right-handed pitching), bullpen fatigue during stretches without off-days, and home/away performance gaps all feed into line pricing. The season's competitive landscape also matters: vig tends to be tightest during the first weeks of the season and around the All-Star break when public attention peaks, while September roster expansion and postseason baseball can introduce both sharper lines and wider margins on less familiar matchups.

Frequently Asked Questions
What are the best MLB lines today?
The table below shows which sportsbook has the best available price on each side of every upcoming MLB event. Line shopping across multiple books can save you 1–3% per bet compared to sticking with a single sportsbook.
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.
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.
