LA Galaxy preserved their perfect record Tuesday, while Alonso Zamora led Tigres' late rally.
The LA Galaxy made it two wins in as many CONCACAF Champions League matches courtesy of a thumping 5-0 victory at home against Comunicaciones.
Captain Robbie Keane and striker Alan Gordon both bagged braces, while midfielder Mika Vayrynen was also on target as the Galaxy continued their dominant start to Group D on Tuesday.
The Galaxy kicked off their continental campaign with a 5-1 humbling of Central two weeks ago, and the reigning MLS Cup champions produced another comprehensive display against the Guatemalan visitors at StubHub Center in Carson, California.
