Cerro Porteno took sole leadership of the Paraguayan Apertura after inflicting a third successive defeat on Rubio Nu, this time by a 5-3 scoreline.
The hosts raced out of the blocks in Asuncion and scored three unanswered goals in the opening 25 minutes though Santiago Salcedo, Edgar Benitez and Mariano Uglessish.
Rubio hit back with a strike from Roberto Acuna in the second half but Luis Caceres restored Cerro's three-goal cushion just 10 minutes later.
And although a late flurry of goals in the final five minutes - two of them scored by Rubio through Josias Cardoso and Alberto Espinola and one in response from Guillermo Beltran - gave the scoreline a closer look, it was Cerro who emerged as comfortable winners.
They now lead by a single point from Libertad and Olimpia, who enjoyed victories against Sol de America and Nacional Ascunion respectively.
Olimpia left it late to secure their 2-1 home win, with Maximiliano Biancuchi netting the winner in the 87th minute after Nacional's Ariel Bogado had cancelled out Luis Caballero's opener.
Libertad were much more comfortable 3-0 winners at Sol de America, with Luciano Civelli, Sergio Aquino and Jose Nunez all on target for the away side.
Guarani enjoyed the biggest victory of the weekend as they eased past Tacuary 4-0 on Friday evening thanks to goals from Fabio Escobar, Dario Ocampo, Dante Lopez and Luis De la Cruz.
Meanwhile, Jorge Ayala scored twice and Eduardo Echeverria once as Sportivo Carapegua won their first ever match in the Primera Division, beating winless Indendiente FBC 3-0.
Newly-promoted Cerro Porteno also went down 3-0 at Sportivo Luqueno, with Guido Di Vanni netting a brace and Juan Abente also scoring, while Cesar Caceres missed a penalty to extend the advantage further.
