Normally reliant on a sturdy back line to protect the goal, D.C. United Women topped the North Jersey Valkyries 2-0 last night by virtue of an offensive strike from a stalwart on that same defensive line. D.C. back Jerica DeWolfe scored the ultimate game-winner in the first half, with midfielder Hayley Siegel notching the insurance goal in the second, to earn the victory at the Maryland Soccerplex.
