 In 1999, the league expanded to 12 teams, with the addition of the Altoona Curve and the Erie SeaWolves.The two divisions were restructured and renamed for the 2010 season, as the Eastern Division and the Western Division, because the Connecticut Defenders moved to Richmond, Virginia, after the 2009 season, where they are now known as the Richmond Flying Squirrels.The start of the 2020 season was postponed due to the COVID-19 pandemic before ultimately being cancelled on June 30.
