Via tweet from Carrie Muskat, the Cubs have postponed tonight's game with the Padres and will play a day/night doubleheader tomorrow:
#Cubs game Tuesday is ppd. They will play day-night doubleheader on Wed. First game, 1:20 pm CT, second at 6:05 pm CT
Doesn't seem like a whole lot of time between games, and further, the weather's not supposed to be that much nicer tomorrow. I'll have more info as it becomes available, but with that scenario, people who have tickets to tonight's game would use them for the night game -- the 1:20 game would be as regularly scheduled. I'll update this post when more info is out there.
And this is your official rainout thread. Discuss amongst yourselves.
