This series was essentially decided in the first leg, where Santos picked up a 6-2 away win; the Guerreros made five changes to the starting lineup for this game and it did not affect their dominance one bit. They had chances from the opening whistle, but it took 18 minutes to find the breakthrough. Marlos Moreno made it 1-0 on the night (7-2 aggregate) with his header.
That goal opened the floodgates and it took just three minutes for Santos to add another. In the 21st minute, the hosts hit the post with a free kick, and Julio César Furch pounced on the rebound to make it 2-0 (8-2).
Ulises Rivas then made it 3-0 (9-2) in the 31st minute when he finished off a low cross from Moreno, who was having a very good game.
Marathón was completely unable to respond to the pressure and generated very little going forward.
The pace of the game slowed in the second half, but Santos was still able to run the score up. In the 81st minute, the aggregate reached double digits with Eduardo Aguirre’s header to make it 4-0 (10-2).
Then, in the 85th minute, Diego de Buen converted a penalty kick to give Santos the definitive 5-0 (11-2) win.
With the 5-0 (11-2 aggregate) win, Santos advances to the quarterfinals to face the New York Red Bulls, while Marathón is eliminated.
