Reverting to the format used from 2012-17, all regular-season matches played amongst participants will count toward the Cascadia Cup standings in 2023. Each of the three teams will play six games, meaning they won’t have an equal number of home games against each opponent.
The supporters’ groups from the Seattle Sounders, Portland Timbers and Vancouver Whitecaps announced the format change on Tuesday. In 2018 and 2021, the Cascadia Cup teams also played six matches against one another, but only the last home game against each opponent counted toward the Cup standings in effort to balance the home schedules.
