Mike Magee opened the scoring for last season’s best performed regular season team in the 40th minute with a neat finish from a perfect Robbie Keane pass from the left side of the penalty area.
Just after the hour-mark, it was 2-0 when Keane powered home a stooping header from Bryan Jordan’s cross from the right before Magee wrapped up proceedings with an inch-perfect header from another clinical Jordan pass 15 minutes from time.
The win allowed the Galaxy to go seven points clear of second-placed Seattle Sounders with five matches remaining prior to the play-offs and extended their recent run to four wins in five matches.
