The Dallas Burn beat the Chicago Fire, 1-0, then dropped a 2-0 decision to Colorado Saturday in preseason action.
Guest player Philip Salyer, who left the University of Maryland to play for German club Werder Bremen's amateur team, had the winning goal against Chicago.
Casey Schmidt, drafted out of Boston College, had both goals for the Rapids in their 2-0 win.
The Burn used a number of guest players, including Barbados international Gregory Goodridge, former Trinidad & Tobago star Jerron Nixon, veteran Spaniard Ivan Iglesias and Paul Dalglish, the son of former Scottish star Kenny Dalglish.
