Baseball Betting 101: Understanding MLB Betting Odds

I think one of the single biggest misunderstandings that the DFS community and the general public has is where betting odds come from and how they are shaped. To be clear: THEY DO NOT COME FROM VEGAS! To understand betting odds it is important to understand the life cycle of a line.


Life Cycle of an MLB Money Line

  1. BetOnline (BOL) is almost always the 1st to open MLB numbers. They generally do this by 3PM the day before. Don’t be fooled though. These lines are as soft as they come and only low limit action is allowed on them. They do this mostly for PR reasons and the openers at BOL have 0 reliability for understanding a team's implied odds. As soon as 1 of the 2 big boys open up numbers (Pinny or CRIS), BOL moves numbers to match. If your market is small enough you can find nice value on these lines since the limits are too small for the sharps to hit they generally remain soft until the real numbers open. You should never use BOL numbers for anything DFS related.
