Using the MLB run line bet type as an example if the Oakland A’s are +1.5 against the Boston Redsox and bettors think it will be a close game and take heavy action on the A’s +1.5 it leaves the sportsbook exposed to lose a lot of money. The reason line movement occurs is because the odds makers need to make the game enticing to bet for both sides. The line movement is tracked from where the line started - otherwise known as the “open” - to where the line either currently sits or where it finishes known as the “close”.
These bets can be on the MLB spread, the money line, or the over under, it doesn’t actually matter the bet type because all baseball betting features line movement. MLB line movement occurs when money comes in on one side or another in any given game. Betting line movement is one of the most important aspects of baseball betting.
