Liga will play Brazil's Fluminense in the finals scheduled for Nov. 25 and Dec. 2, in a rematch of the 2008 Copa Libertadores finals where Liga became the first champion from Ecuador. Liga eventually beat Fluminense in a penalty shootout.

After the Copa Libertadores, the Copa Sudamericana is the second most important club tournament in South America.

Liga's 7-0 home win overturned the 2-1 loss in the first leg at Montevideo a week ago.

Claudio Bieler scored a hat trick, and Carlos Espinola, Miller Bolanos, Edison Mendez and Ulises De La Cruz earned the other goals.

Bieler opened the scoring from the penalty spot in the 18th minute after Neicer Reasco was brought down in the box.

Espinola headed Edison Mendez's corner past diving River goalkeeper Luciano Dos Santos in the 28th, and River's defense collapsed in first-half stoppage time when Bieler's looping cross was headed back across goal by Walter Calderon for an unmarked Bolanos to smash into the roof of the net.

Mendez scored Liga's fourth with a clean strike from outside the box in the 57th, and De La Cruz made it 5-0 in the 78th.

Bieler completed his hat trick in the 84th and 89th minutes.
