Kofi Opare and Chris Rolfe's second-half goals helped DC United see off Orlando City 2-1 on Wednesday to extend their undefeated MLS streak to eight games.
It's DC United's longest unbeaten run since 2007, but Cyle Larin gave Orlando City the lead in the 11th minute, lasting until the 70th minute when Opare leapt over his marker and headed in Taylor Kemp's free kick.
Rolfe, who was brought on in the 54th minute, stretched to touch home Miguel Aguilar's chipped pass 11 minutes from time.
DC United are now undefeated in 14 straight league home games, and sit top of the Eastern Conference with 21 points from 10 games.
