RSK lost 2-1 to Costa Rican club Saprissa on Tuesday, but progressed to the final 3-2 on aggregate after winning the first leg 2-0 at home.
When Luis Cordero scored from 30 yards for Saprissa a minute into the second half, RSL fans had to be nervous about how their team would handle the pressure in a hostile environment. But RSL continued to play soccer and push forward and they were rewarded in the 61st minute when Jamison Olave scored from a corner. The valuable away goal meant that Saprissa now needed three goals to progress.
They managed one when Alonso Solis scored from the penalty spot, but it was too late and RSL now move into the final.
There they will face one of two Mexican clubs in the final. Cruz Azul and Monterrey play Wednesday in the other second-leg semifinal. Monterrey leads 2-1 after the first leg.
The winner of the final will represent CONCACAF in the Club World Cup later this year.
