The Colorado Rapids closed out their preseason trip to South America Tuesday in Babahoyo, Ecuador with a 2-1 loss to Emelec, a team the Rapids played to a scoreless draw nearly two weeks ago.The Rapids led 1-0 at the half Tuesday thanks to rookie defender Guy Melamed. The former Israeli youth national team player joined the fray on a corner kick in the 18th minute and headed a goal into the upper right corner to give the Black-and-Blue the early lead. Emelec, however, came back with two goals in a 16-minute span in the second half to reverse the Rapids' advantage. The first goal came in the 70th minute, when a miscommunication between Rapids defender Nat Borchers and goalkeeper Byron Foss led to an own goal. A well-placed shot to the far post beat Foss in the 86th minute to give the local side the victory. The Rapids' first-year head coach Fernando Clavijo said he is happy with the club's progress over the course of their South American excursion. "I'm pleased with what we achieved during this part of our preseason," said Clavijo. "The fitness aspect of the team is on the right track to reach the level that we want for the beginning of the 2005 season. The past three weeks we have focused on that aspect of our team, the next five weeks will be focusing on the soccer aspect of the club." The Rapids return to the United States Wednesday, flying into Fort Lauderdale, Fla., for a five-day stay in the Sunshine State. The club will play the Haitian national team, which Clavijo previously coached, on Sunday at Lockhart Stadium in Fort Lauderdale.
