Despite RSL taking the lead through Fabian Espindola's brilliant 45th minute header, the Galaxy managed to fight back at The Home Depot Center when David Beckham found Chad Barrett with a long ball and the LA striker was able to flick home under extreme pressure just prior to the hour-mark.
With just under 20 minutes remaining, the Galaxy hit the front when Beckham's long free-kick was flicked on by Paolo Cardozo to Todd Dunivant at the back post and his cross back into the area came off two RSL defenders, the last touch off Nat Borchers, for a winning own goal for the home side.
Thierry Henry was on the scoresheet with a classy 13th goal of the season but it was not enough as New York Red Bulls drew 1-1 with Toronto FC who were served by Danny Koevermans' fifth goal in six matches. NYRB's play-off chances took another blow as they now sit fifth in the East, four points behind third-placed Columbus Crew who won 2-1 at home over DC United.
Elsewhere in MLS, Sebastien Le Toux netted twice as Philadelphia Union beat DC United 3-2 in the Washington clubs first of two weekend matches on Friday night whilst Houston Dynamo and Chicago Fire drew 1-1.
And in last night's match, Juan Pablo Angel was on target with a late leveler as Chivas USA held Philadelphia to a 1-1 draw in the Union's catch-up game.
