1918 Dayton Triangles season

The 1918 Dayton Triangles season was their sixth season in the Ohio League. The team finished with a known record of 8-0 and won their first Ohio League title. However, many of the top teams in the league did not field teams this season due to the outbreak of World War I and the Spanish flu pandemic, both of which led to the opening of the season being postponed until the middle of October.
