Guarani won their fourth Paraguayan Division Profesional match in a row, thrashing Cerro Porteno 4-1 away from home.
Fernando Jubero's league leaders took the lead at the Estadio General Pablo Rojas in Asuncion courtesy of a stunning second-minute strike from Dario Ocampo.
The Argentine midfielder trapped a half-clearance from the Cerro defence, before he danced past a defender and buried a shot from outside the area into the left side of the net past a diving Diego Barreto in goal.
The visitors doubled their lead in the 35th minute, Eduardo Filippini finishing a fine move from their own half after Fernando Fernandez laid a ball out to the right from the top of the area.
Fernandez got on the scoresheet himself in the 62nd minute, powering past a hapless Barreto after being released behind the Cerro defence.
Juan Aguilar's curling free-kick was Guarani's fourth, before Cerro scored a consolation goal via Rodolfo Gamarra.
