Javier Morales scored on a header in the 53rd minute and Real Salt Lake beat Chivas USA 1-0 on Saturday night.
Salt Lake (3-3-2) moved one point ahead of Chivas into second place in the Western Conference.
Chivas USA (3-3-1) has now lost two straight games while failing to score a goal in either match.
Less than minute after Olmes Garcia clanked a shot off the crossbar for the second time Alvaro Saborio recovered the ball and sent a cross into Morales near the left post. Morales tapped in the header and gave Salt Lake 1-0 lead.
The go-ahead goal from Morales came after a huge defensive play prevented Chivas USA from taking control before halftime.
Nick Rimando came up with a huge save for Salt Lake in the 36th minute after a handball on Ned Grabavoy set Chivas up with a penalty kick.
Edgar Mejia lined up to take the kick and booted the ball toward the right post. Rimando perfectly anticipated the direction of the kick and batted the ball away at the post to keep it scoreless. It marked Rimando's 18th career save on penalty kicks.
Rimando, who has given up just five goals in seven games, earned his second shutout of the season.
Morales came close to tacking on another goal in the 88th minute. He lobbed a free kick over a three-man defensive wall at the top of the box. The ball was on frame and pushed away by Dan Kennedy at the top corner of the left post.
Emotions boiled over for Chivas in the final minutes. Chelis, the team's first-year head coach, had words for Morales as he subbed out with two minutes left. He had to be restrained by the fourth official and exited through the players' tunnel shortly afterward.
Mejia followed up by being ejected with a red card during the fourth minute of stoppage time for fighting. He will be suspended for Chivas' next match.
Salt Lake played without team captain Kyle Beckerman in the lineup. Beckerman was sidelined after dislocating a rib in practice last week.
