The Seattle Sounders limp into Portland Sunday for a big rivalry match against the Timbers. They're experiencing their longest winless streak since their expansion year of 2009.

KPLU sports commentator Art Thiel says the Sounders need an attitude adjustment if they hope to beat Portland and move one step closer to the coveted Cascadia Cup.

The Seattle Sounders are winless in their last six Major League Soccer matches, playing to a 1-1 draw Wednesday night against Sporting Kansas City at CenturyLink Field in Seattle.

That's not the best record to bring into a heated regional rivalry with the Portland Timbers on Sunday, as both team vie for the coveted Cascadia Cup.

KPLU sports commentator Art Thiel will have more on this tomorrow morning at 5:35 and 7:35 on 88.5 KPLU. Check back here for a blog of our conversation.
