WASHINGTON — Juan Pablo Angel had a goal and an assist and the Red Bulls improved on their best start in franchise history by beating D.C. United 2-0 yesterday.

Salou Ibrahim also scored for the Red Bulls (5-1-0), who won at RFK Sta dium for the first time since 2005.

New York had been 0-2-5 in seven previous meetings there.

United (0-5-0) is off to its worst start. D.C. was winless in its first four games in 1996, the MLS inaugural season.

Ibrahim beat defender Juan Manuel Pena to Dane Richards’ low cross to score in the 51st minute, side-footing a second effort past goalkeeper Troy Perkins.

Angel started the sequence with a pass to Richards on the right.

Nine minutes later, Angel reached Joel Lindpere’s long free kick, and nodded it inside the left post.
