3 Jackie played baseball in 1944 for the Kansas City Monarchs in the Negro American League where he was noticed by Clyde Sukeforth, a scout working for Branch Rickey who was the club president and general manager of the Brooklyn Dodgers. Rickey had the secret goal of signing the Negro Leagues' top players to the team. Although there was no official ban on blacks in organized baseball, previous attempts at signing black baseball players had been thwarted by league officials and rival clubs in the past, so Rickey operated undercover. Robinson drew national attention when Rickey selected him from a list of promising candidate’s and signed him. In 1946, Robinson was assigned to play for the Dodgers' minor league affiliate in Montreal the Montreal Royals.
