West Demerara giant Den Amstel squeaked past Santos by a 1-0 scoreline to clinch their quarterfinal berth when the Guyana Football Federation (GFF)/Kashif and Shanghai Super-16 Championship continued on Sunday at the National Training Centre, Leonora.
A solitary conversion settled the physical encounter, which was dominated and highlighted by rugged defending.
Darren Niles of Santos recorded the only noteworthy moment of the opening stanza, as he was denied by the goalkeeper in the 22nd minute.
