Make yourself a rule to follow on how much juice you are willing to pay at most. For me I have a rule of not paying higher than -180 chalk. I don't care how good a pitcher is or how sure a team is going to win, I am not going to bet on any more than -180 line. The biggest thing about baseball is understanding juice and finding good value lines that will help you profit in long run. If you are going to bet on all the favorites all the times, chances are you will lose in a long run because of the juice. Learn how to bet on underdogs and good values. That way you can go 2-2 on the day and still make profit compared to betting on favorites and losing money. Another thing about baseball is don't blindly bet on Ace pitchers. Just because they are
Aces don't mean they won't lose. Like Halladay tonight, -330 juice line ended up losing to Astros. Learn to avoid high juice and you will be fine.
