They spent their first years barnstorming across the country, sometimes playing doubleheaders in different states on successive days. They officially joined the Negro National League in 1936, where they played until their final season in 1948. Hall of Famer Satchel Paige had a stint with the Black Yankees, and other notable players from the team include “Fats” Jenkins, Ted “Double Duty” Radcliffe, and “Mule” Suttles. \nThe New York Black Yankees Sport Twill Cotton Jersey stays true to the designs of the era, with period-correct lettering and logos. It’s crafted with a lightweight twill that retains the hard-wearing durability of vintage wool jerseys but is easier to wear and easier to wash. \nIn partnership with the Negro Leagues Baseball Museum (NLBM), we are proud to offer this cotton twill jersey. A portion of proceeds from this product will support the NLBM in Kansas City.
