The Cardinals will wear upgraded powder blue alternative uniforms during Saturday away games beginning with the 2019 season. It has red piping and "St. Louis" underneath the "birds on the bat" insignia, same as the Saturday home cream alternatives. The new jerseys are designed by Adidas and feature mesh across the front and back for maximum ventilation. The Cardinals have worn white uniforms since their inception in 1882. They will continue to do so until they retire number 10 in the memory of owner Bill DeWitt Jr., who died last year at 100 years old. Number 10 was retired throughout baseball on April 15, 1969 in honor of the late player who died the previous year at the age of 39. He had been diagnosed with cancer two years earlier. The Cardinals have one of the most unique uniform traditions in all of sports. When they first began playing games in St. Louis, the team wore black uniforms with a white crescent moon and six stars in honor of their location within Missouri's star-shaped flag. These uniforms were used through the 1896 season. Then in 1897, when the Cardinals moved into their current stadium (now known as Sportsman's Park) in downtown St. Louis, they adopted a new color scheme: red caps and jackets with white stripes down the sides and a black base with red pinstripes.
