The biggest game in Seattle Sounders history started off a little nervy, it’s fair to say. Although the Sounders ultimately beat Pumas UNAM 3-0 in the second leg of the CONCACAF Champions League — 5-2 on aggregate — and looked pretty comfortable doing it, the opening half provided more than enough reason to worry. Seattle created chances early, but lost Nouhou in the 11th minute and João Paulo in the 29th to injuries. Both sides pushed, but at each turn Stefan Frei and his defense stood up to the challenge and kept Pumas out. Then in the final minute of first half regulation time Raúl Ruidíaz did what we all knew he would: he hammered a ball in the area that beat the goalkeeper after a deflection.
