The United Shore Professional Baseball League was founded by Andy Appleby, a former senior vice president of the Detroit Pistons and Palace Sports and Entertainment.

Justin Orenduff, a former first round pick of the Los Angeles Dodgers, is the former Director of Baseball Operations.

The league has four teams based in Metro Detroit, with all games being played at Jimmy John's Field in Utica, Michigan.

League revenue comes primarily from sponsorship partners and other advertisements, ticket sales and ballpark concessions.

During the 2019 season, pitcher Randy Dobnak became the first alum to advance all the way to the Major Leagues when he was called up to the Minnesota Twins on August 8, 2019.
