[U.S. OPEN CUP] D.C. United won the battle of MLS last-place teams when it beat FC Dallas, 4-2, in the preliminary round of the U.S. Open Cup at RFK Stadium on Wednesday night. Adam Cristman led D.C. with two goals, while 17-year-old Andy Najar had a goal and an assist.

D.C. United Curt Onalfo was red carded in the first half and missed most of the offensive fireworks.

Najar had set up Cristman, who chipped FCD goalie Kevin Hartman five minutes into the game.

Onalfo was ejected in the 32nd minute and missed five goals over the next half hour.

Hartman had a nightmare in goal, getting fooled on Salvadoran Christian Castillo's 40-yard free kick to make it 2-0 six minutes before half.

Cristman returned the favor and set up Najar to make it 3-0 before Dallas drew close on goals by Bruno Guarda and Dax McCarty.

Cristman closed out the scoring when he beat Hartman again, heading Clyde Simms' pass into an empty net.
