The golden trio of Beckham, Robbie Keane and Landon Donovan combined to seal the deal, with the American deftly chipping his shot over and around the out-rushing Tally Hall, the Houston Dynamo keeper.
It looked like the footballing gods were not shining favourably on the team from Tinseltown after Adam Cristman missed at least a couple of glaring opportunities, while Scotsman Adam Moffat missed an equally gifted chance at the other other end for Houston.
The Home Depot crowd were in top form with a record crowd packed into the Los Angeles stadium and on 74 minutes they went berserk after a Beckham head-flick was met by Keane who jinked one way, then the other, before releasing the ball into the path of Donovan inside the box who nipped the ball over the outstretched arm of Hall about eight yards out.
Beckham tried to round of his Galaxy career with a tremendous free kick with moments remaining and although it was net-bound, Hall got his hand to it, to tip it over the bar for a corner.
The game ended in jubilation for the Galaxy players and supporters and gives the side their third MLS Championship trophy, the first since 2005.
They were favourites beforehand to emerge victorious from this match and this faith was not unjust as they dominated the match from beginning to end, looking the favourites to score throughout the match.
Commiseration's go to the Texas side who had fought valiantly to reach this stage but just fell short at the final stage. After a 3-1 victory over the Galaxy just a few short weeks ago, hopes were high of a repeat but a third title for the Houston side never materialised.
However, with a new stadium currently being finished in downtown Houston and a near to perfect season just completed, the future looks bright for the Orange Crush.
What happens to Beckham now is anyone's guess. PSG in France look the favourites to land him, but who knows, he may return to LA again next season for a final hurrah!
