Javier Hernandez netted a double to silence the San Jose Earthquakes crowd as LA Galaxy triumphed 3-2 to boost their playoffs aspirations on Saturday.

The former Mexico international took his season tally to 17 goals, mimicking a clown when celebrating both his goals in retaliation to a pre-game San Jose tifo that read: "The LA circus – same clowns, different costumes".

The result moves Galaxy up two places into fifth in the Western Conference on 46 points from 32 games, having secured back-to-back wins for the first time in MLS since April.

Julian Araujo's right-side ball for Hernandez led to the opener in the 12th minute, with the ex-Manchester United forward poking home.

Gaston Brugman doubled Galaxy's lead in the 42nd minute, capitalizing on a sloppy turnover to rifle in a rocket in off the underside of the bar.

Hernandez added their third in the 69th minute, producing a classy finish after Efrain Alvarez threaded an excellent ball into the box for him.

Cristian Espinoza pulled a goal back in the 74th minute, converting a penalty he won after before brought down by Galaxy goalkeeper Jonathan Bond before Hernandez fizzed a chance for his hat-trick wide.

The Earthquakes grabbed another goal in the fourth minute of stoppage time when Nathan's deflected header went in from Miguel Trauco's bouncing volley but it was mere consolation for the west's bottom side.
