Local colleges and universities also use Pullman Park for some of their home games. Some of these schools include Butler County Community College, Clarion University, and Penn State Greater Allegheny. Tournaments have also been hosted by Atlantic Coast Baseball and West Penn Elite.

The stadium's official home team tenant is the Butler BlueSox of the Tri-State Collegiate League.

1934–2004
Pullman Park opened for the 1934 season. It hosted minor league baseball from the late 1930s to the early 1950s. Notable players such as Lou Gehrig, Joe Dimaggio, and Whitey Ford played at the stadium while the Yankees farm team (Butler Yankees) was in Butler. Joe Namath, Terry Hanratty, and Rich Saul also played at Pullman during their high school years. The ballpark itself was named after the Pullman-Standard Company's railroad car manufacturing facility which sat adjacent to the ballpark from 1902-2005.

2005–2008 Renovation
The ballpark closed after the 2004 baseball season, and sat vacant for two years while necessary funds were raised to rebuild it. Construction began in the fall of 2007, and work was completed in June 2008.

The New Pullman Park
On July 2, 2008, Pullman Park hosted a boxing match, televised on ESPN2. Butler native, Brian Minto knocked out John Poore 2:23 in the first round of the main fight. The match was the first major event to be hosted at the ballpark after the restoration and the first nationally televised event in Butler.

The following summer saw Pullman Park get its first major full-time baseball tenant in almost 60 years, the Prospect League's Butler BlueSox. The BlueSox went 28(W)-26(L) during their inaugural season at the ballpark. To date, the BlueSox have played eight full seasons at the stadium. Pullman hosted the USCAA's Small College World Series on May 6–9, 2013, and the Prospect League All-Star Game on July 17, 2013.
