This was the 8th time the MLB all star game "mid summer classic" had been played. It was held in St. Louis Missouri at Sportsman's Park on July 9, 1940. The NL was led to victory by the lone home run of the game by Max West of the Braves and they won the game 4–1. The two starting pitchers of the game were Red Ruffing of the New York Yankees for the American League who took the loss for this game and Paul Derringer of the Cincinnati Reds for the National League who got the win in this game.
The starting rosters for the both the National League and the American League are shown below:
At this time there was also a separate professional baseball league composed primarily of African American and Latin baseball players which was called the Negro League. These leagues were created for minorities to play professional baseball because of the racism at the time that would not allow certain races to play in the Major Leagues.
