Quick-fire goals from Sebastian Ubilla and Gustavo Canales lifted Universidad Chile to their first victory in the group stages of the Copa Libertadores this season, a 3-1 win at home to 10-man The Strongest.

But the Chilean giants finally opened their Libertadores account thanks to Gustavo Lorenzetti, Ubilla and Canales at Estadio Nacional Julio Martinez Pradanos in Santiago.

Universidad Chile were forced to do it the hard way, though, after Pablo Escobar gave the Bolivian visitors a 17th-minute lead via a curled effort beyond goalkeeper Johnny Herrera.

The hosts hit back three minutes later courtesy of Argentinean midfielder Lorenzetti, who fired a half-volley into the bottom corner of the net from the edge of the penalty area.

The Strongest were reduced to 10 men in the 55th minute when Walter Veizaga saw red for a second bookable offence.

And Universidad Chile took full advantage with Ubilla heading his team in front in the 71st minute before Canales sealed the points seven minutes later.

Cesar Valoyes opened the scoring for Juan Aurich in the sixth minute, blasting the ball into the roof of the net from the edge of the area.

Christian Ramos doubled the lead in the 23rd minute after the poking the ball past Carlos Lampe following a goalmouth scramble.
