Michelle Krill Field at Historic Pullman Park is a baseball stadium located in Butler, Pennsylvania.

Constructed in 1934, and rebuilt in 2008, the ballpark hosted minor league teams that were affiliated with the New York Yankees, Cleveland Indians, Detroit Tigers, and the Pittsburgh Pirates.

The stadium's official home team tenant was the Butler BlueSox of the Tri-State Collegiate League, before relocating prior to the 2025 season.

The following summer saw Pullman Park get its first major full-time baseball tenant in almost 60 years, the Prospect League's Butler BlueSox.

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.
