Who was the first african-american major league baseball player and what team did he play for?

Moses Fleetwood "Fleet" Walker (October 7, 1856 – May 11, 1924) was an American baseball player, inventor, and author. He is credited by some with being the first African American to play Major League Baseball.[1] Walker played one season as the catcher of the Toledo Blue Stockings, a club in the American Association. He then played in the minor leagues, until 1889, when professional baseball erected a color barrier, that stood for nearly 60 years, until the game was once again integrated, with the rise of Jackie Robinson, in 1947, which brought an end to the segregated Negro Leagues. After leaving baseball, Walker became a businessman and advocate of Black nationalism.
