Maykel Galindo scored off a feed from Chukwudi Chijindu in the 15th minute, and Eduardo Lillingston added a goal late in added time in Chivas USA's 2-0 victory over the reeling New York Red Bulls on Saturday night.
Chivas (9-7-3) ended a losing streak at five games and moved into a tie with Colorado for third place in the Western Conference.
The beleaguered Red Bulls, an MLS-worst 2-16-4, dropped their sixth straight league match and are winless in 14 consecutive MLS games since beating San Jose on May 8.
The loss also clinched the Red Bulls' worst season since 1999, when, playing as the MetroStars, they posted a 7-25 record.
Chivas got on the scoreboard when Chijindu made a fine run up the right flank and served a 30-yard crossing pass to Galindo, who beat Red Bulls goalkeeper Bouna Coundoul to the left side of the goal for his third goal of the season.
Chivas, which entered the game having scored just two goals in its last six contests, played conservatively the rest of the way, not taking any major chances and focusing on the defensive side.
Zach Thornton made four saves to record his eighth shutout of the season, tying him with Houston's Pat Onstad for the league high.
