The blue is similar to what the Cardinals wore in the 1982, though it appears now in the Saturday home style — with a script "St. Louis" and the red piping around the buttons and on the sleeves.
"That look represented an era," said team president Bill DeWitt III. "I should ask around. The guys in the clubhouse were, 'Dude, you've got to do that.' So I got to thinking we have a Saturday alternate, so (now) we have a Saturday alternate on the road. It's the modern jersey, but it recalls earlier eras."
The announcement is the first substantive change to the jersey since the Saturday home jerseys were introduced in 2012.
