MLB Postponed Games Records: A Historical Search

Question
Some friends and I have been researching a question with no luck.  Can you help us find the MLB records for postponed games in a season?

Answer
Sam,

Sorry, I don't have the answer.

I'd suggest looking for "The Sporting News" Record Book.  You probably don't need a recent copy because I'm guessing this record was set quite a long time ago.  Baseball fields drain so well now, that there just aren't that many rainouts.

Hope this helps!
