Commanded his box with some key punches, though he perhaps could have been more authoritative on the sequence leading to Yedlin's goal.
Got forward well and helped keep possession. Seattle did start finding space on his side in the dying stages, though.
Made a perfectly timed late run into the box before nodding home Portland's third. Was solid defensively until Johnson beat him in the air for Seattle's second.
Was his usual pesky self, winning aerial challenges and denying service to Seattle's forwards. Didn't let a first-half yellow card hinder his aggressiveness.
Distributed well, tackled aggressively and clogged passing lanes, coming up with the interception that created Valeri's tally. Sent Gspurning the wrong way while confidently converting his penalty kick.
Did well to contain Dempsey, though he did receive a yellow card for an unnecessary foul with Portland enjoying a four-goal aggregate lead. Won second balls and got into the attacking third more than usual.
Was nearly flawless in possession, picking out his passes and attacking pockets of space on the dribble. Always a dynamic threat.
Was dictating Portland's attack from the beginning, teeing up Wallace and Chara for early opportunities that weren't converted. Capped a beautiful buildup on the Timbers' second goal with an incisive run into the box and finish.
Had to be kicking himself after pushing a golden early opportunity wide, but found redemption when he slipped in Valeri on Portland's second and hit the cross to Danso for goal No. 3.
Picked up right where he left off in the first leg, burning Seattle's compact diamond midfield by taking the space out wide. Earned the penalty kick with one bold run into the box, then helped set up Valeri's goal with another.
Returning from suspension, Gspurning wasn't directly at fault on any strike but could have done better on the second and third Portland goals.
Was the only Seattle defender to turn in a decent performance, ending the shutout with a goal at the far post before setting up Johnson's tally with an exquisite cross.
Was slow to react on Valeri's goal, then got caught woefully out of position when a quick restart led to Danso's strike.
Called for a penalty kick when he needlessly flung his arm at the ball in the corner of his box, then failed to react as Danso beat him to a cross for Portland's third goal.
Produced some fine moments pinching inside from his role on the right flank. Maintained his aggression even as the deficit continued to grow, and set up a goal with a long throw for the second straight game.
Didn't fare much better than Leo Gonzalez, who had his own struggles at left back in the first leg. Was lucky not to receive a pair of yellow cards for reckless challenges.
Struggled mightily for the second straight game on the left flank of Seattle's diamond midfield, conceding acres of space wide for Portland to expose. Also had a bad giveaway that led to the Timbers' second strike.
Couldn't rediscover the magic of 2009, when the career holding midfielder thrived up top. Looked thoroughly uncomfortable before being lifted shortly after halftime.
Sprayed a few nice passes but didn't control the game to the best of his ability. Isolated deep in the diamond midfield, Alonso was over-matched by the Chara-Johnson duo.
Was denied service for most of the match but he made his mark late, setting up Yedlin's goal with a flick-on header before emphatically nodding home a strike of his own.
Again showed a few creative flourishes and put himself in some good spots, but didn't have the final touch. We'll have to wait until next year to see what Dempsey is truly capable of in a Sounders jersey.
