It was a triumphant finale to 37-year-old Beckham's American odyssey, though when he made the move from Real Madrid in 2007 he had claimed he was partly motivated by the chance to promote his sport in the USA.
He has yet to reveal where he will play next, though he has no shortage of lucrative offers awaiting his attention. But regardless of his destination, he claims the MLS will remain important to him.
"This is very special for us. To win at our own home is fantastic," he said.
"I always said I was going to stick by it. When I'm committed to something I'm committed to the end.
"It's sad that it is the end; this has been a special place for me and continues to be special to me.
"I'm happy to have been part of this for nearly six years and to have been successful with this club for four years.
"I'm going to continue my commitment to this league, this country and this sport. My commitment stays the same to growing this league and growing the sport in this country."
Asked where he would be playing next, Beckham responded by playing to the fans in California's Home Deport Centre.
"I have no idea, what's more important is that I'm happy I'm wearing this (Galaxy) uniform today."
