Erick Torres scored two goals, the first on a penalty kick, and Chivas USA upset the visiting New York Red Bulls 3-2 on Sunday.
Julio Morales also scored to help Chivas (5-14-6) win for the first time in more than a month and for only the second time since the end of March. Chivas had not scored more than one goal in a game since April 27, a span of 16 games.
Goalkeeper Dan Kennedy made two big saves and defenders Marky Delgado and Bobby Burling saved shots off the goal line for Chivas.
''For me, this was our best game of the season,'' said Chivas USA coach Jose Luis Real, who took charge in early June.
''I've only been here for half of the season, but this is definitely the best game Chivas has played since I've been here.''
Tim Cahill and Dax McCarty scored for the Red Bulls (11-9-6), both from Thierry Henry assists. New York would have claimed the top spot in the Eastern Conference with a victory.
''No disrespect to Chivas, but we're a much better team than they are,'' New York coach Mike Petke said.
''This is MLS, the parity is proven. Any team can win on any day. ... We could have done better with our opportunities. It just wasn't the day to score.
Morales scored in the 30th minute for Chivas, but the Red Bulls evened it a minute later, when Cahill headed Henry's corner kick into the net off the left post.
Chivas again went ahead in first-half stoppage time, with Torres converting a penalty kick after he was barreled over in the Red Bulls box by center back Ibrahim Sekagya.
Torres extended the lead in the 81st minute, turning on a rebound after Kosuke Kimura blocked a Carlos Alvarez shot.
McCarty headed in a Henry free kick in the 86th minute, and Cahill nearly evened the score deep into stoppage time, but Burling saved his shot at the right post.
Kennedy made two one-on-one stops on Fabian Espindola in the first half, both set up by Henry passes, and Delgado had a goal-line save on a Cahill header off the corner kick that followed the second of Kennedy's big stops.
Torres nearly had a hat trick, but he hit the left post from Carlos Bocanegra's pass in the 69th minute.
