The USA star scored his 12th goal of the season in the 1-0 home win over reigning MLS Cup champions Colorado Rapids in Week 26 action to give the Galaxy a nice break on second-placed Seattle Sounders who dropped points at home on.
Donovan equaled Thierry Henry at the top of the MLS Golden Boot chart when he finished a neat move that involved David Beckham, Chad Barrett and Sean Franklin to fire into the bottom corner from the edge of the penalty area in the 36th minute.
With six regular season matches remaining, the Galaxy are in a great position to finish with the best record in MLS for a second season running.
The Sochaux loanee opened the scoring in the 11th minute with a sliding finish at the back post for his first goal since June 25 after Chris Pontius was played through by Dwayne De Rosario before making it 2-0 four minutes later when he received another pass from Pontius following a Chivas defensive error to hammer home.
The treble was complete, and the match wrapped up, in the 66th minute when DC took off on a fast-break with Pontius advancing into the final third and slotting into the path of Davies who finished with ease.
Elsewhere in MLS, Real Salt Lake managed to defeat the Sounders 2-1 at CenturyLink Field for the Seattle clubs first loss in seven games. Both sides had a player sent off in the first half as Alvaro Saborio scored the winner for RSL in the 56th minute.
Teal Bunbury scored twice to guide Sporting Kansas City to a 3-0 win at home over Houston Dynamo, Toronto FC grabbed just their fifth win of the season with a 4-2 result at Columbus Crew who have leaked 10 goals in their last two matches, New England Revolution defeated FC Dallas 2-0 at home as San Jose Earthquakes had the same scoreline over Chicago Fire.
