A runline is MLB baseball’s version of a point spread. In NFL and NBA point spreads, the betting odds are usually at a standard of -110, and the spread itself is typically moved to balance action. In baseball, the spread itself is fixed at -1.5 runs, and the attached odds are changed to balance action. Baseball run lines are typically listed as the favorite -1.5 runs or the underdog +1.5 runs. In other words, the favorite has to win the game by at least 2 runs rather than just winning the game. These MLB baseball sportsbook betting odds significantly alter the money line of the game.
An explanation why you would play the MLB baseball run line, instead of the official line:
Martinez is pitching for Boston and opposing Meadows for Kansas City. The money line is Red Sox -320 and the baseball run line, is Red Sox -1.5 -150. This means that you can bet Red Sox to win the game by more than one run and only have to lay $150 to win $100 rather than the $320 to win $100 with a straight money line wager.
These are the types of situations that I look for to use baseball betting odds, or run lines. It has been my experience that using baseball sportsbook odds, or run lines, with heavy favorites can be an effective way of betting on the heavy favorite without having to risk a heavy loss. By taking your time and doing some research, you will find that there are many strong pitchers and teams that win big when they win.
Therefore, you can use the baseball betting odds to make these bets more attractive. What this means is that the Boston may be 14-5 with Pedro on the mound and 12 of those victories came by 2 runs or more. Randy Johnson may have a great record but because his games always have huge money lines, you may end up losing money by wagering all of his starts. However, by taking the baseball betting odds, or run line, you significantly reduce the amount of money you must risk.
