The Pickles were charter members of the Great West League, having been founded in 2015 by GWL commissioner Ken Wilson. The Pickles played before 16 sell-outs and to 99% of capacity in their inaugural 2016 season. A month before their second season on April 5, 2017, it was announced that Seattle Seahawks punter Jon Ryan and marketing entrepreneur Alan Miller would become part of the Pickles ownership group, along with members from Rose City Baseball LLC. Former Major League Baseball pitcher and Oregon-native Jeff Lahti took over the managerial role for the 2017 season and the Pickles were eliminated from the Great West League playoffs by the Medford Rogues.
On October 24, 2017, the Pickles announced that they were leaving the GWL and joining the West Coast League. Prior to the 2018 season, Gresham GreyWolves head coach Justin Barchus replaced Lahti as manager. His team won the South Division in the first half of the season with a 17-9 record, securing them a playoff spot in their first year. The Pickles went on to claim the best record in the WCL by going 37-17 overall, but couldn't get past the Corvallis Knights in the first round of playoffs. Justin Barchus went on to win WCL Coach of the Year along with Kelowna Falcons manager Brain Donohue.
