Chris Schuler and Paulo Araujo scored goals and Real Salt Lake won its third straight to start the season, beating the New England Revolution 2-0 Saturday night.
New England, which finished down two men, had been unbeaten with a win and three ties coming into the game.
Schuler, a central defender from Creighton University who was making his second start, headed in a corner taken by Collen Warner from the left side in the 27th minute.
Araujo, a 22-year old Brazilian, took a through ball from Warner just beyond the midfield stripe and broke down the right wing, uncorking a 12-yard drive to the short right side past New England goalkeeper Bobby Shuttleworth in the 47th minute.
New England was shut out for the first time this season, having scored a goal in each of its first four matches.
RSL goalkeeper Kyle Reynish made three saves.
New England had two good scoring chances in the first half. Kenny Mansally ripped a 35-yard shot just over the crossbar in the 35th minute, while Pat Phelan's header off of a cross from Kevin Alston veered wide left in the 42nd minute.
In the second half, the Revolution's Marko Perovic hooked a left-footed drive wide left in the 59th minute. His corners in the 49th and 79th minutes went unfulfilled.
New England played the final 20 minutes shorthanded after midfielder Shalrie Joseph was sent off for unsportsmanlike conduct against RSL's Kyle Beckerman. Phelan was shown a red in the 85th minute.
