Moneyline-115-105+$5
Spread -3.5-112-102+$7
Over 217.5-110+100+$15
- Run Line
- Baseball's version of the spread, almost always -1.5 / +1.5. The favorite at -1.5 must win by 2+ runs. Unlike football spreads, the run line rarely moves off 1.5.
- Over/Under (Game Total)
- A bet on combined runs scored by both teams. MLB totals typically range from 7 to 10.5, heavily influenced by starting pitchers, ballpark dimensions, and weather.
- First 5 Innings (F5)
- A moneyline, spread, or total that only covers the first five innings. Isolates starting pitcher matchups and removes bullpen variance.
- NRFI / YRFI
- No Run First Inning / Yes Run First Inning. A popular yes/no prop on whether either team scores in the top or bottom of the first inning.
- Listed Pitcher
- A bet condition where your wager is only valid if the listed starting pitcher actually starts. If a pitcher is scratched, the bet is voided.
- Innings Total
- Over/under on the total number of innings played, which can exceed 9 in extra-inning games.
- Moneyline
- A straight-up wager on which side wins. No point spread involved — you simply pick the winner.
- Vig (Juice)
- The bookmaker's commission built into every line. Standard vig is around -110 on each side, meaning you risk $110 to win $100.
- Implied Probability
- The likelihood of an outcome as suggested by the odds. For example, -200 implies a 66.7% chance. Comparing implied probability across bookmakers reveals where value exists.
- Closing Line Value (CLV)
- The difference between the odds you locked in and the odds at the time the market closes. Consistently beating the closing line is the strongest predictor of long-term betting profit.
- Line Movement
- Changes in odds between when a market opens and when it closes. Driven by sharp money, public betting patterns, injuries, and other news.
- Bankroll
- The total amount of money you've set aside specifically for betting. Effective bankroll management — typically risking 1-3% per wager — is essential for surviving variance.
- Unit
- A standardized bet size, typically 1% of your bankroll. Tracking results in units rather than dollars normalizes performance regardless of stake size.
- Hedge
- Placing a bet on the opposite side of an existing wager to lock in a guaranteed profit or reduce exposure, often used with futures or parlays.
- Parlay (Accumulator)
- A single bet combining two or more selections. All picks must win for the parlay to pay out. Higher potential return but significantly lower probability.
- Futures
- Long-term bets on outcomes determined at the end of a season or tournament, such as championship winners, MVP awards, or win totals.
- Live Betting (In-Play)
- Placing wagers while a game is in progress. Odds update continuously based on score, time remaining, and game flow.
- Overround
- The total implied probability across all outcomes in a market. An overround above 100% represents the bookmaker's margin. Lower overround means better value for bettors.
