The 2018 Cascadia Cup is well underway, and the Portland Timbers will host Vancouver Whitecaps FC on Saturday night in the fourth game of the famous three-way rivalry among the Pacific Northwest's MLS teams (8pm PT | ROOT SPORTS NW).
Created by the supporters of the Sounders, Whitecaps and Portland Timbers, the Cascadia Cup has been around since 2004. It was contested by all three teams in USL until 2009, when the Sounders made their MLS debut. The Whitecaps and Timbers continued battling for the Cup in the lower divisions until 2011, when both moved up into MLS, allowing the Sounders to get back in on the competition.
