Seattle halted Tigres's 13-match unbeaten streak with a come-from-behind win in the Champions League quarterfinals.
At halftime the result looked unlikely. Leading 1-0 from the first leg, a largely reserve Tigres side took the lead in CenturyLink Field. Elias Hernández finished off the chance created, in part, by U.S. international Jonathan Bornstein, who found Alberto Acosta down the left flank.
However, a second yellow to Manuel Viniegra for kicking the ball away gave the Sounders a lifeline, and the MLS club took advantage, notching three in the second half.
"We like to participate in this game, but the level of referee that we have in the CONCACAF zone doesn't really match the expectation that a tournament like this should have," Tigres coach Ricardo Ferretti said.
Rookie DeAndre Yedlin scored his first professional goal with an impressive one-time volley off a half-cleared corner early in the second stanza. Djimi Traore made it interesting on the hour mark by hitting a screamer from 30 yards out that clicked off the crossbeam on its way in.
Eventually Eddie Johnson scored the essential third to overcome the away goals rule, beating Jorge Diaz de León at the near post.
"Obviously you can't say anything but outstanding things about all three goals," Seattle coach Sigi Schmid said. "Those were some fantastic goals by DeAndre, but Djimi Traore, and by Eddie Johnson."
Liga MX-leading Tigres lost for the first time since October to bow out of the competition. Seattle will now face either Santos Laguna or the Houston Dynamo.
