The contest was the second leg of a two-game, total-goal series.

The teams played to a scoreless draw last week in Carson, California.

Tigres advance to face another Mexican side, either Club America or Cruz Azul, in the two-legged semifinals.

The latter two clubs were set to complete their quarterfinal series later tonight.

Romulo Zwarg also scored for Tigres.

Joseph Paintsil and Carlos Garces replied for the Galaxy.

In the ninth minute, Tigres’ Diego Lainez delivered a cross from the left flank, and Ibanez knocked in a glancing header to open the scoring.

Just over a minute later, Antuna fired home a 12-yard goal with a left-footed shot off an assist from Rafael Carioca.

Paintstil took advantage of a Tigres giveaway in the back to score into a largely vacated net in the 40th minute, but Romulo restored the hosts’ two-goal advantage with a header in the 57th minute.

Garces scored in the 60th minute after a knockdown on a corner kick.
