When did Major League Baseball (MLB) hold its first night game?

The first night game in Major League Baseball (MLB) history occurred on May 24, 1935 when the Cincinnati Reds beat the Philadelphia Phillies 2–1 at Crosley Field. The original plan was that the Reds would play seven night games each season, one against each visiting club. Night baseball quickly found acceptance in other Major League cities and eventually became the norm.

The first big-league team to play games at night was the 1930 Kansas City Monarchs of the Negro Leagues (not part of the MLB organization) who often played against the House of David baseball team, who carried portable lights mounted on trucks along with their team bus. The Monarchs first night baseball game was on April 28, 1930. It was an exhibition game in Enid, Oklahoma against Phillips University.
