The Chicago Cubs used Opening Day on Thursday to raise awareness for the war in Ukraine -- flying Ukrainian flags at Wrigley Field and donating raffle proceeds to war victims.
Cubbies officials hung the Ukrainian flags all outside of the stadium ... with roughly a dozen of the flags being placed around the famous venue's facade.
Inside the stadium, Chicago donated proceeds from the 50/50 raffle to Ukrainian relief efforts.
The team also had Ukrainian American Youth Association Choir hit the field before the game against the Milwaukee Brewers to sing the Ukrainian national anthem.
