The Pittsburgh Sports League (PSL) is a social enterprise housed within PUMP . The PSL is the premier provider of adult, mainly co-ed, recreational sports leagues in the Pittsburgh region. Founded in the fall of 2000, PSL started as a flag football league of 150 participants. Today, the PSL provides over 20,000 unique participants with an opportunity to play and socialize making it PUMP's largest social networking program. A majority of PSL sports, 18 in all across 4 seasons, are played within the city limits; however, the PSL extends outside the city limits as well.
