The new trend in baseball in the 1940’s was to install lights for night games. The Braves (then known as the Boston Bees) had not invested yet. Probably a good thing. They played their first night game at the Polo Grounds. It was May 24, 1940. They lost 8-1. The next week they lost in the lights at Forbes Field. There were only two teams that year without lights.
It really didn’t matter in 1940 whether they played in the lights or not. They ended the season, under Casey Stengel as manager, in 7th place. They were 34 1/2 games behind with a 65-87 record.
