MLB offers one of the most analytically rich betting environments in professional sports. With a 162-game regular season running from late March through early October — followed by an expanded playoff bracket — the sheer volume of games creates deep, liquid markets across moneylines, run lines, totals, and an extensive array of player props. Unlike football or basketball, baseball's low-scoring nature and game-to-game variance make it a sport where small edges compound over a large sample. The prominence of the starting pitcher in determining game outcomes gives sharp bettors a clearly defined variable to build models around, while the sport's detailed statistical record — stretching back over a century — provides a rich foundation for analysis.

Moneyline margins in MLB tend to be tighter than in many other major sports, largely because sportsbooks compete aggressively on a product with high betting volume and a sophisticated customer base. Typical vig on MLB moneylines ranges from around 2.5% to 5%, though this varies meaningfully by book and by the perceived competitiveness of the matchup. Lopsided games between mismatched teams often carry wider margins, while evenly matched pitching duels tend to see tighter pricing. Totals and run lines generally carry slightly higher vig than moneylines. Bettors who shop across multiple books can meaningfully reduce the juice they pay over the course of a full season — and given MLB's volume, even a fraction of a percentage point saved per wager adds up substantially.

Several key factors drive line movement and create exploitable inefficiencies throughout the season. Starting pitcher changes — whether due to injury, rest, or bullpen management — can shift a moneyline by 30 cents or more. Weather conditions, particularly wind direction and humidity at outdoor parks like Wrigley Field or Coors Field, materially impact totals. Platoon splits, home/away performance differentials, and bullpen fatigue during heavy stretches of the schedule all matter. Odds tend to be sharpest in the middle of the season when books have the most data to work with, while early-season lines and postseason markets — where sample sizes shrink and public money surges — often present the most opportunity for disciplined bettors to find value.

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.
