Six days after suffering one of the most embarrassing losses in its 12-year history, the Los Angeles Galaxy achieved one of its greatest successes.

The Galaxy upset Mexican champion Pachuca, 2-1, in their opening game of the SuperLiga on Tuesday and made amends for its 3-0 loss to Tigres in David Beckham's first game with the club since his presentation.

Beckham watched from the stands as his new MLS club held off Pachuca, winner of the 2006 Copa Sudamericana and 2007 CONCACAF Champions Cup.

Alan Gordon scored his first goal of the season for the Galaxy in the 50th minute, and Landon Donovan scored the game-winner in the 81st minute on an assist from Cobi Jones.

Donovan's goal came three minutes after Rafael Marquez had tied the score.
