FYI (sorry for the "b" word) In the history of baseball, we find that the bases were originally centered on a 90' square, causing them to be split in fair and foul territories. Because of the problems this caused, the 'foul' edges of home "circular" plate were chopped off giving it it's current point. (At some time before or after this, home went from round to square.) Also, first and thrid were moved so that the center of he base was no longer at the 90' mark, but not the furtherest outside corner is. Second base is the only one retaining it's original placement and shape. Softball bases not have this same layout pattern.

Or at least this baseball fact is what I heard on PBS.

ASA changed the rule this year. Check which rules you are playing by. In ASA once the BR has reached 1B. The doule base becomes 1 whole base. The runner can retun to either part.
