The league features four teams and all games are played at Charles B. Walker Stadium at Lents Park in southeast Portland, home of the Pickles.

Months prior, the Pickles also founded a developmental farm club of their own known as the Portland Gherkins.

[1][2][3][4][5] The Pickles and Gherkins were joined by the previously independent Gresham GreyWolves and West Linn Knights and played the inaugural two-week season at Bob Brack Stadium in Aurora, Oregon, with all players, coaches and staffs having to follow the COVID-19 guidelines at the local, state and federal levels and limited fans in attendance.

[12][13] The league was so successful that it announced a second season and that all of its games would be moved to Walker Stadium at Lents Park in southeast Portland, home of the Pickles, who returned to the WCL.

The Knights were folded and both were replaced by the revived Portland Rosebuds (named for the former Negro league team from the 1940's) and Willamette Wild Bills.

[23] On August 26, the Willamette Wild Bills won their first WWWL Championship by beating the defending champion Gherkins 9-8 to capture the title.
