D.C. United bolstered its training camp roster Tuesday by selecting three players in the MLS supplemental draft.

Without a first-round pick, United used the seventh selection of the second round to claim New Mexico defensive midfielder Lance Rozeboom. It selected Charlotte center back Charles Rodriguez in the third round and Drake midfielder Matt Kuhn in the final stage.

Rozeboom, an Iowa native, was a three-year starter for the Lobos. [Brief video here.] Rodriguez, from Tennessee, was the Atlantic 10 defensive player of the year in 2010 and helped the 49ers advance to the NCAA final in 2011. Missouri-born Kuhn, an academic all-American with a 4.0 GPA as an accounting major, led the Bulldogs with 11 goals last season.

Last week, with its only selection in the MLS SuperDraft, United acquired Louisville midfielder Nick DeLeon with the seventh overall pick.

The club has also reportedly taken interest in 6-foot-4 goalkeeper Carl Goody, an England native who played at William Carey University in Mississippi. United General Manager Dave Kasper confirmed Goody has been invited to training camp.

United opened preseason workouts this week in Washington and will begin training in earnest next week in Florida.
