Mack Park was the original home field of Detroit's Negro National League baseball franchise, the Detroit Stars. It was constructed in 1914 by Joe Roesink, sponsor of a local semi-professional team, a Dutchman of Jewish descent born in Grand Rapids who owned a chain of haberdasheries.
The park, was located on the east side of Detroit, about four miles from downtown, at the southeast corner of Fairview Ave. and Mack Ave., after which it was named. The park was located in what was then the heart of the city's German community, some distance from the city's African American neighborhoods of Paradise Valley and Black Bottom, which were closer to downtown. However, the ballpark was easily reached from those areas via the Mack Ave. streetcar line.
Mack Park's single-decked structure, constructed of timber and tin sheeting, was built to seat 6,000 occupants; however, varying reports suggest as many as 10,000 could fit in the stadium's wooden bleachers. The park is said to have had cozy confines, having a short right field porch and power alley. This may have artificially inflated power hitting numbers of left-handed hitters, despite the high fence in right field. The park has been called a haven for home run hitters and a nightmare for pitchers.
In 1915, the new Federal League sought to locate a franchise in Detroit and contacted Roesink about operating a franchise out of Mack Park; he stalwartly declined the offer. Three years later he accepted an offer from Chicago sports promoter Rube Foster to establish a Negro National League franchise in Detroit and use Mack Park as its home field.
Before 1920, the Detroit Stars' first season of play, the park played host to teams like the Boston Braves, New York Giants, Philadelphia Phillies, and Brooklyn Dodgers. It was common in those days for major league teams to play minor league or semi-professional baseball teams on their off days to generate additional revenue.
