MLB moneyline betting is the most straightforward way to wager on baseball: pick the team that wins the game, regardless of margin. Unlike football or basketball, where point spreads dominate the market, baseball's low-scoring nature makes the moneyline the primary betting vehicle. Run lines (baseball's version of a spread, fixed at 1.5 runs) exist as an alternative, but the moneyline remains where the sharpest action and deepest liquidity concentrate, making it the market where sportsbooks compete most aggressively on price.
Strategy-wise, MLB moneyline betting rewards bettors who focus on starting pitching matchups, platoon splits, and bullpen workload — particularly during the dog days of summer when fatigue creates exploitable edges. Underdogs win roughly 42-44% of MLB games, making plus-money plays more viable than in most other sports. Because the moneyline is baseball's flagship market, vig tends to be thinner here than on run lines, totals, or player props, where books often build in wider margins. Even small differences in juice — the gap between -110/-110 and -108/-108 — compound significantly over a full 162-game season, making line shopping on moneyline prices one of the highest-value habits a baseball bettor can develop.

Frequently Asked Questions
Which sportsbook has the lowest MLB moneyline vig?
Caesars currently has the lowest vig at 2.22%, earning a grade of A.
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.
Are there reduced-juice options for MLB?
Yes. Reduced-juice books like BetAnySports and LowVig.ag consistently price MLB below the -110 standard. Bet105 prices -105 across every sport including MLB, for a market hold of roughly 2.4% — advertised book-wide pricing that would place it in the most-efficient tier, though it is not yet part of our measured feed.
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.
