A drab 0-0 tie against the Seattle Sounders was enough to return the Philadelphia Union to the top of the Eastern Conference, level on points with DC United.
The point Philadelphia gained left the Union and DC United tied on 24 points, but Philadelphia has the better goal difference.
The draw snapped a three-game winning streak for the Union who had got the better of FC Cincinnati, the New England Revolutions and Toronto FC.
In turn DC United were falling to the Houston Dynamo, 2-1 at the BBVA Compass Stadium.
Wayne Rooney gave the visitors the lead just after the half time break only to see Memo Rodriguez and Thomas McNamara score a minute apart later in the half.
Rooney had the easiest of chances when he opened the scoring, turning in a Ulises Segura cross at the far post.
Rodriguez equalized with a shot that it appeared goalie Bill Hamid in the DC United net should have saved although there was little the United keeper could do with the second as McNamara arrive to bundle home a bouncing cross from Adam Lundqvist.
Next Saturday the Union will return to action when they host the Portland Timbers at the Talen Energy Stadium.
That's also the venue the following Wednesday when the Western Conference cellar dwellers, the Colorado Rapids, arrive in town.
Meanwhile DC United travel to Gillette Stadium in Foxboro to face the New England Revolution, and new manager Bruce Arena, also on Saturday and then host the Chicago Fire four days later.
Seattle are 12/1 to win the MLS Cup this season, with Los Angeles FC 3/1 and DC United 10/1.
