It's been raining all day here in Minnesota, and it's not looking like there will be a game tonight. I've gotten no official confirmation, but it appears to be just a matter of time before an announcement is made.
Both the Twins and Orioles are off on Monday, but it appears that the two teams would play a double header tomorrow rather than playing the postponed game on Monday's off day.
Hopefully, I'll have more on this soon, but it doesn't appear like you'll get Orioles baseball tonight.
