TORREON, Mexico — Darwin Quintero scored two of his three goals in the first 26 minutes and Santos opened its bid for the CONCACAF Champions League title with a 5-0 win over Aguila on Tuesday.

Last-season's runner-up to Monterrey, Santos also had goals from Gerardo Lugo and Daniel Luduena to win for the 18th time in 19 games at home in the Champions League.

The result was the second lopsided defeat for tournament debutante Aguila, which was beaten 5-1 by Toronto FC on August 1 at BMO Field.

Santos, which made only four lineup changes from its 2-1 loss to Pumas on Saturday, dominated from the start. Los Guerreros had their first shot within three minutes, took the lead on Quintero's first goal in the sixth minute and established a 4-0 advantage by halftime.

Quintero, who had four goals in the Champions League last season and three in the 2010-11 season, put Santos ahead in the sixth minute. He settled a ball from just inside the Santos half from Kenyi Adachi, trapping it touch at the 18, taking another touch to get around Aguila keeper Benji Villalobos, who had come well off his line, and simply rolled it into the net.

His second came after a Luduena free kick from 30 meters was tipped onto the right post by a diving Villalobos. The ball caromed off the post, struck Villalobos in the back and dropped on the goal line. Quintero darted in and outraced Aguila defender Mardoqueo Henriquez to knock it over the line.

Santos, which ended a three-game winless streak with the result, next travels to Toronto on August 28. Aguila, outscored 10-1 in its two games so far in the Champions League, will not play again until hosting Santos on September 19.

XELAJU 1, CHIVAS DE GUADALAJARA 0: At Quetzaltenango, Guatemala, Edgar Chinchilla converted off a corner in the 67th minute and Xelaju beat 11-time Mexican league champion Chivas de Guadalajara in the CONCACAF Champions League.

Both teams had a goal disallowed for offside in the second half before Chinchilla made a near-post run, outleapt Hector Reynoso and deflected Aleljandro Alpizar's corner past Chivas keeper Luis Michel into the far-side netting.

Chivas was making its first appearance in the Champions League since the reformulated championship was inaugurated four years ago. The match was played on the 50th anniversary of Chivas' only CONCACAF club championship, when it defeated Comunicaciones to win the inaugural Champions Cup.

The goal came against the run of play, with Chivas having more of the possession but neither side was able to create many quality chances.

The victory was Xelaju's first in the Champions League.
