A common question that arises when betting on baseball, is what constitutes a good line? Most of the time (though the Yankees were well over average in 1998, and the Marlins below) baseball teams will win between 40% – 60% of their games. The baseball bettor must determine what they believe are the chances of a team beating another in a given situation, and then relate that to what- price is being given by the bookmakers.
The following is a breakdown of what percentage of plays at a given price must win, just for a bettor to break even:
|Line||% Needed to win||Line||% Needed to win|
