Totals betting in the KBO — picking whether the combined runs scored by both teams will go over or under a posted number — requires a different calibration than MLB totals. KBO games tend to feature higher scoring environments due to smaller ballparks, a livelier ball, and generally shallower pitching depth beyond each team's ace. Posted totals frequently sit in the 8.5 to 10.5 range, and bettors who apply MLB-based intuition without adjusting for these structural differences will consistently misjudge value.
The totals market becomes most exploitable when weather data, particularly wind direction and humidity at specific venues like Sajik or Gwangju, diverges from what the line implies. Tracking bullpen usage across back-to-back series is another edge, since KBO relievers are worked hard and fatigue patterns show up quickly in run production. Regarding vig, KBO totals often carry slightly wider margins than sides or moneylines — books price in the added uncertainty of high-variance offenses. Bettors shopping across multiple sportsbooks can frequently shave 5-10 cents off the juice, making line comparison particularly worthwhile in this specific market.

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.
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 every hour, on the hour (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 average vig: A+ (under 2%) is exchange-level pricing, A (2–3%) very competitive, B+ (3–4%) above average, B (4–5%) the industry standard, C+ (5–6%) slightly below average, C (6–7%) below average, D (7–8%) high vig, D− (8–10%) very high, F (10%+) predatory.
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, BetAnything). 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 every hour, on the hour (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.
