MLB totals — the over/under on combined runs scored — are among the most analytically rich markets in sports betting. A typical game total sits between 7 and 9.5 runs, and because baseball outcomes are heavily influenced by identifiable, quantifiable factors, sharp bettors often find totals more exploitable than moneylines or run lines. Starting pitcher matchups are the most obvious driver, but bullpen workload, ballpark dimensions, weather conditions (particularly wind direction at Wrigley or Coors), and lineup construction against left- or right-handed pitching all create edges. Games featuring a late-season bullpen day or an opener strategy frequently see the most market disagreement, which is where value tends to cluster.
Vig on MLB totals generally runs slightly higher than on moneylines, with standard juice set at -110 on both sides. However, there's meaningful variation across sportsbooks — some regularly post -105 or even +100 on one side of a total, which compounds into significant savings over a full 162-game season. Because totals betting tends to involve high volume for serious MLB bettors, even a few cents of reduced vig per wager can materially impact long-term profitability. Comparing prices across books before placing any totals bet is one of the simplest, most effective edges available.

Frequently Asked Questions
What is a totals (over/under) bet?
A totals bet is a wager on whether the combined score of both teams will be over or under a number set by the sportsbook. For example, an NFL total of 47.5 means you're betting whether the final combined score will be 48+ (over) or 47 or fewer (under).
How does totals vig compare to other markets?
Totals vig varies by sport but is generally moderate — between moneyline and spread vig. Totals attract less volume than spreads but more than most prop markets, putting them in a middle ground for vig. Weather and injury news can cause totals to move significantly, sometimes affecting vig.
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 exceptional and rare — these are typically sharp-friendly books. A (2–3%) is excellent. B+ (3–4%) is above average. B (4–5%) is the industry standard for most recreational sportsbooks. C (5–6%) is below average. D (above 6%) indicates high-juice markets where bettors face a steep cost per wager.
- 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.
