The Posse had a mix of good and bad seasons. They made it to the championship series in their first two seasons, losing best-of-five series to the Long Beach Barracudas in 1995 and 1996. After finishing last in their division in 1997 and 1998, the Posse finally won a championship by defeating the Chico Heat in a best-of-five series in 1999.^[1]

The Posse disbanded ahead of the 2001 season. The Pasco City Council signed a 10-year agreement for the Portland Rockies (one of the Colorado Rockies' minor league affiliate of the Colorado Rockies) to take over the Posse's stadium.^[3] This team, renamed as the Tri-City Dust Devils, continues to play in the Tri-Cities as of 2025^[update].
