In sportsbetting an the '''underdog''' is the side of a team betting market that the market perceives as having has a less likely smaller perceived chance to winof winning. Often abbreviated ''[[dog]]'', the underdog will have carries a positive [[plus moneypoint spread]] and yields a [[moneylineplus money]] odds and a positive return on the [[point spreadmoneyline]]. The other side of the same market that with a greater perceived chance of winning is known as the [[favorite]]. == Underdog moneyline == As underdogs are perceived as having a greater lower chance of winning relative to the favorite their [[moneyline]] yields a larger return. [[American odds]] format displays underdog moneylines with positive numbers. A team with +200 odds of winning carries a 33.3% [[implied probability]] and yields a $200 profit on a $100 initial risk (for a total return of $300). In the example below the Baltimore Ravens are the underdog. They have +160 moneyline odds which carry a 38.5% implied probability. A $100 initial risk would yield a $160 profit for a total return of $260. {| class="wikitable" style="text-align: center; margin: auto;"|- style="background-color:#eaecf0;"|colspan="2"|'''Team'''|'''Spread'''|'''Total'''|'''Moneyline'''|-|[[File:Patriots.png|25px]]|New England Patriots| -3.5 (-110)| Over 44.5 (-110)| -180|-|[[File:Ravens.png|25px]]|Baltimore Ravens| +3.5 (-110)| Under 44.5 (-110)|style="background-color:#E2FFD3"| +160|} == Underdog spread == In order to balance the perceived skill discrepancies between competing teams a point spread is used. The underdog being viewed as the weaker team is known given a positive spread. The points they are given are applied to the final score in order to determine if the bet wins. A bet on an underdog's point spread will win if they either win outright or lose by a margin smaller than the spread. Using the same example as before the Baltimore Ravens have a +3.5 point spread with -110 odds. A bet on the Ravens spread would win if they either win the game outright or lose by 1-3 points. Because the point spread is being used to balance the perceived ability of both teams the betting odds are normally equal around -110. This means a $110 risk would yield $100 profit for a total return of $210. {| class="wikitable" style="text-align: center; margin: auto;"|- style="background-color:#eaecf0;"|colspan="2"|'''Team'''|'''Spread'''|'''Total'''|'''Moneyline'''|-|[[favoriteFile:Patriots.png|25px]]|New England Patriots| -3.5 (-110)| Over 44.5 (-110)| -180|-|[[File:Ravens.png|25px]]|Baltimore Ravens|style="background-color:#E2FFD3"| +3.5 (-110)| Under 44.5 (-110)| +160|}
