The Lehigh Valley Black Diamonds were a proposed Atlantic LeagueIndependent baseball team who were originally slated to play at the Lehigh Valley Multi-Purpose Sport Complex, a 6,400-seat, $15 million-dollar ballpark in Williams Township. Construction was halted by developer Jim Petrucci when the team owner, Thomas Flaherty, filed for Chapter 11 bankruptcy on February 1, 2000, with some $3 million in debts. Bankruptcy records showed 128 people submitted claims for $52,683 in season ticket sales. The Lehigh Valley Multi-Purpose Sport Complex was demolished in early 2005, without ever hosting a single baseball game.
