Dwayne De Rosario scored two first-half goals as D.C. United downed Toronto FC, 3-1, on Saturday night in Major League Soccer at RFK Stadium.
De Rosario scored just 57 seconds into the match against his former squad, and notched a second goal two minutes before halftime to send United on its way to its fifth home win this season.
United (7-4-3) dropped its home opener to Sporting Kansas City, but has strung together a seven-match undefeated streak in the District of Columbia with five wins and two draws.
Toronto FC (0-9-0) extended its own league record for losses to begin a season to nine games, and moved closer to the overall record of 12 straight defeats.
De Rosario, who played for TFC from 2009 until early last season, scored under a minute into the match when he reached a Branko Boskovic free kick and headed into the bottom-left corner.
United doubled its lead before half when Josh Wolff sent the ball to the right to Chris Korb, who squared a pass back into the middle for De Rosario to drive the ball into the net from seven yards for his fifth goal this season.
Danny Koevermans pulled Toronto within a goal in the 71st minute, but D.C. was back in front by two goals just two minutes later when Andy Najar set up Hamdi Salihi, who scored his fourth goal in his last five games to seal the win.
D.C. wraps up a three-game homestand May 26 against the New England Revolution and Toronto will try to end its slide May 26 against the Philadelphia Union.
