Originally home to an American Association franchise, Exposition Park later became home to the Pittsburgh Pirates. When the Pittsburgh Alleghenies joined the American Association in 1882, they decided to build a new ballpark along the Allegheny River, across from what became downtown Pittsburgh, and eventually the site of Three Rivers Stadium and PNC Park. After a couple of years of playing baseball at Exposition Park, the Alleghenies began playing at Recreation Park. The Pittsburgh Alleghenies became the Pittsburgh Pirates of the National League on April 30, 1887. The Pirates played their first game at Exposition Park on April 22, 1891. A covered single tier grandstand extended from the first base side to home plate, and down the third base side. Uncovered bleachers extended down both the first and third base lines. Their was also standing room in right field, and additional seating was on top of the covered grandstand. Because Exposition Park was near the Allegheny River it flooded many times. It also had its roof ripped off two times. After Barney Dreyfuss bought the Pirates, he decided that the club needed a new ballpark. The Pirates last game at Exposition Park was on June 29, 1909. The next day the Pirates moved into Forbes Field. Exposition Park was later demolished is now part of the site of the Pirates current home PNC Park.
