Round-up: Food poisoning paralyses Paraguayans
Guarani won 4-1 at 3 de Febrero and closed the gap on leaders Libertad to one point with one match each to play in the Clausura championship.
Relegation-threatened 3 de Febrero said that seven of their players were hit before the match by a bout of food poisoning which was blamed on a juice drink mixed with vitamins.
"This needs to be investigated," said coach Pedro Nelson Fleitas. "We don't know if the product was past its sell-by date of if somebody put something intentionally in the juice."
Defender Juan Ortiz was treated in hospital and several other players missed the game.
Gilberto Palacios scored twice for Guarani while Federico Carballo and Jonathan Fabrro, from a penalty, notched the other goals for Guarani. William Schuster replied for the hosts.
Libertad, attempting to win their fourth consecutive title, were held 1-1 by Nacional. Juan Samudio put Libertad ahead and Julio Ortellado equalised.
Deportivo Italia won the first stage of the 2008/09 championship with two matches to spare when they beat Aragua FC 2-0 away.
Cristian Casseres and Mauro Conocciari scored in each half to send Italia eight points clear of second-placed Caracas FC, who suffered a 2-0 home defeat by Monagas.
Deportivo Italia qualified for the end-of-season final where they will meet the winners of the second stage which starts in January. Italia will take the title automatically if they win the second stage as well.
