Johnstown Mill Rats

The Johnstown Mill Rats joined the Prospect League in 2021 and play their home games at Sargent’s Stadium at the Point in Johnstown, Pennsylvania. Led by General Manager Sarah Rex and Field Manager Sean Stevens (2025), the Mill Rats are a relatively young franchise looking to establish themselves in the league.

While they haven’t yet reached the playoffs or won any championships, the Mill Rats are steadily improving. Their best season came in 2022 with a 29–31 record.
