Major League Baseball dominates the American sports conversation during the summer as the only major league to run from the end of the NBA Finals and Stanley Cup Finals in mid-June until college football begins in late August. Sports bettors interested in placing wagers during the summer months have daily options in MLB, with teams typically playing six or seven games each week, not including the All-Star Break in mid-July, which also gives bettors more opportunities to wager on events like the Home Run Derby.

MLB Sports Betting Terms:

  • MLB odds move regularly due to betting action, injuries, and other factors, but monitoring the MLB odds board is one way to make the best baseball bets possible. Here are several MLB sports betting terms to know:

  • Alternate lines

    Every MLB game has alternate lines, as sportsbooks post different spreads and totals with adjusted odds. For example, if the total of a game is set at 8.5 runs, sportsbooks may offer that game at 7.5 or 9.5 runs with the related juice also moving for those lines. For run lines, an underdog of 1.5 runs may be listed with an alternate line as a 1.5-run favorite with a much higher potential payout.

  • American odds

    American odds are the most common odds used in MLB, with the money line indicating the amount of money needed to win $100 (favorite) or the amount that a $100 wager would pay (underdog). This is one of the three main types of betting odds.

  • Closing line

    The final odds posted when the game begins is the closing line. The live odds will then start to shift after the game begins and will generally continue until the game is over.

  • Consensus

    The consensus line is a combination of odds from the top sportsbooks. If a game has a consensus total of 9, it means that a majority of oddsmakers have the over/under for the game set at nine runs.

  • Decimal odds

    Decimal odds, also called European odds, are one of the other formats used to present betting odds. They represent the amount of money someone would win for every $1 wagered.

  • Favorite

    The favorite is the team expected to win the game outright. Favorites have a negative sign in front of their spread and money line odds.

  • Fractional odds

    British (fractional) odds are the final type of odds used in sports betting. They are the ratio of the profit won to the stake, as a 6-1 underdog would pay $6 for every $1 wagered.

  • Futures

    These can be some of the most interesting odds to monitor, as they relate to things such as World Series winner or division winner. Most sportsbooks update their futures odds on a regular basis, giving fans a chance to see how their team stacks up in the eyes of the oddsmakers.

  • Home-field advantage

    One thing that is a factor in every MLB game is home-field advantage, which changes the odds based on which team is playing at home. Some teams have a bigger advantage than others, as their crowd noise or location can adjust the odds more significantly than others.

  • Hook

    If the betting odds have a half-run attached to them, that is called the hook. The hook makes it impossible for the betting result to end in a tie, as MLB games do not have half-runs.

  • Juice

    Also known as vigorish or vig, the juice is the amount factored into the odds by oddsmakers. An American odds bet of -110 contains $10 of juice for every $100 wagered.

  • Line movement

    MLB odds feature line movement due to various reasons, including injuries, weather or wagers made by professional bettors.

  • Money line

    The money line is the odds related to the winner of the game with no run line involved. Favorites have negative odds, while underdogs have positive odds in an American odds format.

  • Oddsmaker

    Someone who sets betting odds and lines is an oddsmaker. Some oddsmakers create their own betting odds (originators), while other oddsmakers copy odds that are already in the market.

  • Over/Under

    This is one of the primary sets of odds used for MLB betting, with the number representing the expected runs scored in the game. These are also used for some futures odds, such as how many games a team will win in a season.

  • Pick ‘em

    If neither team is favored, the game is called a pick ‘em, signified by both teams having the same money line. The betting odds have not determined a favorite or an underdog, so they are usually good games to watch.

  • Props

    MLB prop betting refers to wagers placed on different aspects of an MLB game aside from the traditional run line, money line and total markets. Player props are the main MLB prop betting markets available, which allow bettors to take positions on statistical categories like a pitcher’s strikeouts or earned runs allowed, a player hitting a home run and other areas of a player’s performance.

  • Run line

    The run line levels the playing field between two teams, as it is the number of runs the favorite is expected to win by. The favorite is designated by a negative spread (-1.5), while the underdog has a positive spread (+1.5).

  • Underdog

    Unless a game is a pick ‘em, every MLB matchup has an underdog, which is the team that is expected to lose. They are denoted by a positive number in the betting odds.

FAQ:

  • What are the types of MLB betting odds?

    The three primary types of betting odds are American (money line), fractional (British) and decimal (European). They are alternate ways of presenting the same odds, offering the same payout in each scenario. The percentage probability of an event occurring can be converted and presented in any of the odds offered.

  • How do I know which team is favored?

    Favorites are always priced with a negative sign in front of their spread or money line, while underdogs have a positive sign in front of theirs. If both teams have negative money lines, the team with the larger negative number is favored. If a team is -1.5 on the run line, they are the favorite and would need to win by at least two runs to cover the spread. Their opponent would be +1.5, needing to lose by one run (or win outright) to cover as an underdog.

  • Who sets MLB odds?

    Odds are originally set by oddsmakers, who are also called sports traders or bookmakers. They usually adjust their odds once bettors start wagering money. The odds can also be moved due to injuries, trades or other factors.

  • Why can I not find baseball odds for a game?

    Sportsbooks take games off the board when a star player suffers an injury or is traded, or another factor occurs. Oddsmakers usually re-post the updated line within a few hours, depending on the severity of the news. The odds are frozen so the sportsbook avoids taking large wagers on odds that are likely to change.

  • What is the total?

    This is another way to reference the over/under, which is the number of runs expected to be scored in a game. If a game has an over/under of 8.5 runs, it will go over the total nine or more runs and under the total with eight or fewer runs. Over/under odds are also used for prop odds, such as a batter’s total bases in a game.
