The 1945 Fenway tryout nobody intended
On April 16, 1945, the Red Sox held a tryout at Fenway Park for Jackie Robinson, Sam Jethroe, and Marvin Williams only because city councilman Isadore Muchnick threatened the permit Boston's teams needed to play Sunday baseball, with Black sportswriter Wendell Smith pressing alongside him. The three players performed well, a voice from the stands reportedly shouted a racial slur telling them to get off the field, and the team never contacted any of them again. Robinson broke the color line with Brooklyn two years later, and the Red Sox became the last major league club to integrate when Pumpsie Green debuted in July 1959.
