D.C. United central defender Perry Kitchen is back at RFK Stadium following two weeks on international duty with the United States Under 20 team. He was greeted to cheers and hugs upon arrival this morning for today's training session with the Black-and-Red. Kitchen was naturally disappointed at his country's exit from CONCACAF qualifying for the 2011 FIFA U-20 World Cup, as the U.S. fell to Guatemala on Wednesday. Said the 18-year-old centerback, "Obviously it was frustrating. It was disappointing, but I'm glad to be back in D.C."
