Video: Harrisburg preview

D.C. United will look to extend its Open Cup run Tuesday night at the Maryland SoccerPlex when the Harrisburg City Islanders come to visit. The USL-2 side is the last club to hand United a loss in the annual tournament, defeating the Black-and-Red 1-0 back in 2007. Tom Soehn and Devon McTavish offer their thoughts on the game.
