United-Red Bulls preview (The Associated Press)

There is always plenty of drama when the New York Red Bulls and D.C United square off but Sunday's match at Red Bull Arena in Harrison, N.J., is for a lot more than just bragging rights and this season's Atlantic Cup. The Red Bulls (12-9-7, 43 points), just a point off of the top of the Eastern Conference table with six regular-season matches left, carry a two-game winning streak and a 10-match run without a loss into play and cannot afford to take a step back. D.C. United (7-9-11, 32 points) have dropped into seventh place in the Eastern Conference two points behind Orlando City for conference's sixth and last postseason berth.
