Paraguay's big derby between Cerro Porteno and Olimpia was marred by red cards for five players and the dismissal of both teams' coaches at the weekend.
The first stage of the Peruvian championship finished with Juan Aurich top and Nolberto Solano's Universitario one point behind in second.
PARAGUAY - Nine-man Cerro Porteno beat eight-man Olimpia 1-0 at home in a match marred by the sending off of five players and the dismissal of both teams' coaches at Asuncion's Defensores del Chaco stadium.
Champions Cerro were already a man short after the first red card in the seventh minute for defender Miguel Torren and had seen their Argentine coach Pedro Troglio dismissed from the bench in the 10th when they took the lead with an own goal by Olimpia defender Dario Caballero.
Caballero's forgettable afternoon began with him being hit by an object thrown from the crowd and suffering a cut to his forehead which caused kickoff to be delayed.
It continued when he and midfielder Claudio Vargas were sent off one minute before half time after fighting among several players. Olimpia coach Carlos Kiese was also sent from his bench.
Defender Oswaldo Vizcarrondo, who had been booked four minutes earlier, followed in first-half stoppage time for a late tackle on Jorge Britez, leaving Olimpia with eight men before the second half.
Kiese slammed referee Carlos Torres, saying: "He hasn't got what it takes to take charge of a 'clasico'; he lacked guts."
Despite their numerical disadvantage, Olimpia were in control in the second half but even after Cerro captain Britez was sent off with 20 minutes to go they could not find an equaliser.
It was a first win in six matches of the Clausura championship for Apertura winners Cerro after four draws. They have seven points.
Olimpia lead with 12 points, ahead of Rubio Nu and Tres de Febrero on goal difference.
PERU - Juan Aurich beat Melgar 3-1 with two goals from Sergio Ibarra to finish top of the first stage of the championship, one point clear of Universitario, 1-0 winners at Jose Galvez, and four ahead of Alianza Lima.
Second-placed Universitario go into the group of even-numbered teams for the second phase, avoiding Juan Aurich and arch-rivals Alianza, who were third.
Sport Huancayo, who finished fourth and will go into the same group as Universitario, crushed Bolognesi 7-0. There were two goals from midfielder Cesar Ortiz and one from 19-year-old Irven "Little Jewel" Avila, who was given a first call-up to Peru's squad last week for World Cup qualifiers next Saturday and the following week.
ECUADOR - Barcelona, Ecuador's most popular club and Libertadores Cup runners-up in 1998, were held 1-1 at home in Guayaquil by El Nacional and can ill afford to drop any more points in their remaining five matches of phase two of the championship.
They are one from bottom of Group A and, more importantly, one from bottom in the overall standings from which the last two go down.
LDU Quito, who won the Libertadores Cup last year, crushed Liga de Portoviejo 4-0 away.
CHILE - Midfielder Milovan Mirosevic scored twice in four minutes as Universidad Catolica opened a three-point lead in the Clausura championship with a 2-1 win over Colo Colo.
Catolica missed a penalty and Colo Colo, one of the country's big two with Universidad de Chile, went one up through midfielder Pablo Magalhaes after an hour.
Mirosevic equalised with a penalty in the 73rd, Colo Colo defender Diego Olate was sent off in the following minute for dissent and the midfielder hit the winner in the 77th.
"The U" beat Audax Italiano 3-2 to leap over them into second place, one point above them. Colo Colo are ninth seven points off the pace.
URUGUAY - Seven-man Central Espanol equalised in the final minute through midfielder Sergio Perez for a 2-2 draw at home to River Plate in the Apertura championship.
They were 2-1 down before midfielder Walter Coelho was sent off in the 38th minute and had three more players sent off between the 81st and 87th.
Champions Nacional beat Tacuarembo 1-0 with a stoppage time header by Diego Vera when a free kick by midfielder Angel Morales came back off the bar. Tacuarembo goalkeeper Alvaro Garcia had been sent off minutes earlier.
