After a scoreless 69 minutes, Osvaldo Alonso scored what looked to be the match winner. Then the Portland Timbers tried to ruin the Seattle Sounders' party with a stoppage time equalizer from Darlington Nagbe.
But in the end, all they did was extend the festivities. Kenny Cooper and Marco Pappa both scored goals in the second half of extra time to seal the win for the Sounders as they advance to the next round of the US Open Cup.
