The Chicago Cubs and Miami Marlins are honoring the victims of last month's mass shooting at Marjory Stoneman Douglas High School with a number of tributes during their season-opening four-game series.
Both teams are wearing patches with the initials "MSD" and 17 stars to honor the number of lives lost in the shooting.
The Cubs will host victims' families and survivors from Stoneman Douglas for Friday's game.
Chicago Cubs first baseman Anthony Rizzo, a Stoneman Douglas alum, said Friday will be an emotional night, as four families of victims or survivors are scheduled to throw out the first pitch.
