according to my site:

Suspended Game Rules for Baseball
For wagering purposes, the score of the last complete inning is the final score. All action on the side will count at that point, and all run lines and total wagers will be cancelled even though the game will be completed at a future date.
All first-half wagers (5 innings) must list both pitchers. If either listed pitcher does not start, wagers on the first half (5 innings) will be canceled.
