 Their fifth straight, they lose that lead and rookie Hurston Kerstad to a concussion. He's on the seven-day concussion injured list. The Birds will try to avoid the sweep in about 90 minutes. They have an early start today, 11-35, first pitch from Camden Yards. Finally, after 11 winless games, D.C. United gets on the board with a victory, knocking off Nashville FC 2-1 at Audi Field.
