OSUMAN29 really it doesn't take five minutes to find out this stuff, you really are being lazy.
Just for you though I have done the simple research. As I thought I was correct in what I said in my previous post a few minutes ago.
For all games in last years post-season the overs / unders were 21 - 11
This is broken down as;
League; 15 - 2 (O/U)
League Champions matches; 3 - 7 (O/U)
World Series; 3 - 2 (O/U)
In years gone past the UNDER has been the way to go. If last year was a freak occurance, only time will tell. Personnal view is I think more games go over than under in the first stage of matches. Most teams are better equipped offensively than pitching.
