Along with finalizing their seeding position in the Audi 2017 MLS Cup Playoffs on Sunday, the Portland Timbers could clinch their fourth-ever Cascadia Cup if they defeat Vancouver Whitecaps FC at Providence Park on MLS Decision Day, presented by AT&T (1pm PT, ROOT SPORTS).
Though Seattle Sounders FC currently sit in first place of the three-team competition on nine points, their Cascadia slate of matches are finished. Should the Timbers defeat Vancouver, Portland would vault Seattle to end at 11 points and claim the cup. A draw, however, will find Seattle claiming it on tiebreakers.
