Western Pennsylvania League

The Class D level Western Pennsylvania League began the 1907 season with eight teams. The Beaver Falls Beavers, Butler White Sox, Clarksburg Bees, Connellsville Cokers, Fairmont Champions, Greensburg Red Sox, Scottdale Giants and the Latrobe, Pennsylvania team were charter members.

On May 28, 1907, the Latrobe team was forfeited to the league. The Cumberland Rooters took its place, but that team moved to Piedmont, West Virginia on June 27, then to Somerset, Pennsylvania on July 11. It eventually folded altogether later that month. On August 1, the Kittanning Infants entered the league, but disbanded, along with Beaver Falls, on August 11, 1907. Greensburg disbanded on August 25, 1907. Fairmont finished in first place with a 68–36 record.^[2] Jim Clark, Dick Hoblitzell and Reddy Mack played in the league.

A league by the same name existed in the late 1889.
