Baseball uses the Money Line, which differs significantly from the pointspread that is used in basketball and football. In baseball you wager according to set odds, based upon the likelihood one teams has in defeating another. For example, the Yankees are the best team in baseball. Kansas City might be amongst the worst. To back the Yankees to beat the Royals you have to lay odds to a dollar, for example 3-1.
Most baseball games are more competitive than our example.
Showing a profit is not as easy it you might think. Winning percentage is not the key to profits. Keep in mind the critical concept that it's the prices of your winners and losers. There will be well over 2,000 major league baseball games played this season. In addition to wagering on which team you think will win the game, you can also wager on whether the total runs scored in the game will be less than or greater than a specified number.
