Lines From Past MLB Seasons

Where can I find lines from past MLB seasons? I used a MLB DOG system a few years ago and it was successful. It's a system that involves only dogs, only in-division matchups and only in April and early May (if I remember correctly). I got away from our beloved sport of wagering for a few years. So I don't know if it would have been successful the past couple of seasons. I want to do some research and see if we may have a good MLB DOG system here. 

Go to MLB Teams click on any team... Say the Baltimore Orioles... Click the Past Results tab... Click the Past Result by Season drop down and pick a year... Say 2011... You can cut and paste the table into Excel and use Text to Columns to split the BAL Line into one column that has Win/Lose and one column that has the MoneyLine...

The best place for an explanation & demo of Text to Columns...

And good luck with your search... I have analyzed the underdog record for all the teams for the last 5 years and could not find a pattern/trend/anomaly that would be worth while to follow.

I was able to find patterns that would allow an extremely modest profit but nothing that would justify the time.

Again... Good Luck and I hope you do find something.

Great info but those are closing lines any site with opening lines in the same format.?  I have not been able to find one since WinnersEdge changed their format from opening lines to closing lines for some reason.

Thanks Rand! I knew it was somewhere around here! I'll let you know if I find anything worthwhile.

that's great info Trigg. TY!
