[MLS] After two straight league games of conceding four goals apiece, D.C. United got the defensive plays it needed to end a bad run.

The attacking trident of Charlie Davies, Josh Wolff and Andy Najar combined for two goals and four assists as United topped Seattle, 2-1, at RFK Stadium Wednesday to end the Sounders six-game unbeaten streak.

Wolff and Davies scored on either side of halftime to build a 2-0 D.C. lead, and though a Brad Evans penalty kick cu t the deficit in half, keeper Bill Hamid and his defenders fended off all other attacks to improve United’s record to 3-4-1.

Davies set up the first goal for Wolff in the 31st minute with a square ball and netted his league-leading sixth of the season in the 52nd when Wolff returned the favor. Both scoring plays were set in motion by Najar, who returned to the starting lineup to earn his first two league assists in 2011.

Fredy Montero earned the penalty kick by drawing a foul that the guilty party, Dejan Jakovic, protested vigorously. But after Evans sent Hamid the wrong way in the 71st minute, the defender shook off his anger to play strongly in the final minutes, during which he hooked clear a ball over the top that nearly set up a great chance for Seattle to equalize.

During the same interval, Hamid tipped over a point-blank header from Alvaro Fernandez and denied Montero with a flying save to his left.

Both teams get back into action on Saturday.

United, a 4-1 loser to Houston last week after being pounded, 4-0, by the Red Bulls, hosts FC Dallas; Seattle (3-3-3) continues its road swing in Columbus.
