Landon Donovan scored the tiebreaking goal on a penalty kick in the 65th minute, and David Beckham left MLS as a two-time champion with the Los Angeles Galaxy's 3-1 victory over the Houston Dynamo in the MLS Cup on Saturday.
Omar Gonzalez tied it in the 61st minute with a long header for the Galaxy, who defended their title in a rematch of last season's championship game.
With a stirring second-half surge capped by Robbie Keane's goal on another penalty kick in injury time, Los Angeles won its fourth MLS Cup, tying D.C. United for the MLS record.
The Galaxy also gave an appropriate farewell to Beckham, the 37-year-old English midfielder who transformed the league and his team over six seasons in Los Angeles. Beckham will play elsewhere in the new year, but he hasn't disclosed his immediate plans.
