It's possible. But also the Royals game is also in a Rain Delay, and they're doing the "Rain Delay" promo as well, so it could be possible that the Cubs and Royals really want to get those games in, if necessarly. I'm sure the Giants and Cubs would rather not play a double-header, given the fact that they'll have to fly to Milwaukee. Edited: It stopped raining in KC, and the game is almost underway, so hopefully the same in Chicago as well. What do you think the attendance will be in KC after a long rain delay? About 16?
