Los Angeles Galaxy beat the New York Red Bulls 2-1 and sealed their berth in the MLS Western Conference final at the Home Depot Center on Thursday.

The Galaxy saw their 1-0 advantage from the first-leg cancelled within the fourth minute as Luke Rodgers was let through on goal by Thierry Henry and the Birmingham-born striker made no mistake with the finish.

The Galaxy rallied and new-signing Robbie Keane found the post after some good footwork in the box before which David Beckham saw a long-range effort fly just over.

It wasn't long before LA leveled. Beckham and Mike Magee seemed to have struck up an understanding and the combination worked again when the latter was at hand to head in a trademark Beckham corner, minutes before half-time.

In the second half, Rodgers found the side-netting, when let through on goal and the miss proved costly. Roy Miller's silly foul on Beckham in the box allowed Landon Donovan to seal a 3-1 aggregate win from the spot.

The Galaxy will now face Real Salt Lake in Sunday's final and will have home advantage.
