Round-up of action from South America
RIO DE JANEIRO, July 31 (Reuters) - A ball boy was blamed for sparking a brawl in a Peruvian match at the weekend while a player was sent off for hitting a stretcher-bearer as a Colombian game also degenerated into violence.
Wilstermann goalkeeper Hugo Suarez turned goalscorer as he converted a free kick in Bolivia and Chile's three biggest teams all lost without scoring a goal between them.
PERU - Alianza Lima blamed the ball boys for provoking the brawl which marred the end of their 3-2 defeat away to Melgar.
Melgar officials also joined in the fighting which ended with riot police on the field in the fourth minute of injury-time at Arequipa's Mariano Melgar stadium.
The trouble began when a ball boy hid the ball from Alianza's Chilean striker Fernando Martel, who remonstrated angrily prompting Melgar players to intervene.
Martel was sent off along with team mate Jose Soto and Melgar's Alessandro Moran.
Charly Valente headed Melgar's winner in the second minute of injury-time after both teams had led.
Waldir Saenz gave Melgar an early lead before Alianza, who won the first stage of the championship, replied through Junior Viza and a Flavio Maestri penalty. Hilden Salas made it 2-2 in the 75th minute.
"The Arequipa people were hostile to us from the moment we arrived... and the ball boys provoked us," said Alianza's Guillermo Salas.
Cienciano, who beat Sporting Cristal 2-1, lead the second stage with six points from three games, ahead of Jose Galvez and Universitario on goal difference. Universitario thrashed Sport Ancash 4-1.
COLOMBIA - Medellin had three players sent off as they lost 3-1 to Pereira.
Eduardo Dominguez, Neider Morantes and Rodrigo Riep were all dismissed in the last 10 minutes, with Morantes receiving his marching orders for attacking a stretcher bearer who was carrying a Pereira player off the field.
Riep was dismissed for fighting with Pereira's Erwin Gonzalez, who was also sent off.
Atletico Junior, who drew 0-0 with Deportivo Cali, lead the Clausura championship with seven points ahead of Atletico Huila on goal difference.
Donaldo Millan gave Huila a 1-0 win over defending champions Pasto, who are without a coach following Oscar Quintabani's resignation last week.
Millonarios beat Quindio 1-0 for their first win of the tournament but it did not impress their fans, who demanded the sacking of coach Miguel Prince.
BOLIVIA - Wilstermann goalkeeper Hugo Suarez scored from a 25-metre free kick as his side won 3-0 away to The Strongest on the opening day of the Apertura championship.
Argentine Daniel Juarez and Edgar Olivares scored the other goals, also from long-range, as the Aviators ran riot in the second half.
Angry The Strongest supporters insulted the players and coach Carlos Chiacor as they left the pitch and a group gathered in front of the main entrance to continue the protests after the game.
Defending champions Bolivar kicked off with a 2-0 win away to Aurora.
CHILE - Defending champions Colo Colo suffered a 3-0 defeat away to Everton, whose coach Marcelo Espina was fired by Colo Colo last year.
Argentine Javier Menghini headed Everton in front following a free kick in the 26th minute before Joel Estay added two late goals. Colo Colo had Arturo Sanhueza sent off for a second bookable offence.
Juan Lorca and Diego Ruiz scored in the first 25 minutes as Huachipato beat Universidad de Chile while a second-half goal from Nicolas Diez gave O'Higgins a 1-0 win away to Universidad Catolica.
Cobresal, O'Higgins, Puerto Montt and Everton lead the four groups after three rounds of games in the qualifying stage.
ECUADOR - LDU's troubles continued as they had two players sent off in a 3-0 defeat away to Emelec.
Armando Paredes scored twice in a five-minute spell during the first half as the Electrics took control and Carlos Quinonez added another in the 84th minute.
Elkin Murillo was sent off before halftime and Alfonso Obregon followed after the break, both for second bookable offences.
LDU, who formed the backbone of Ecuador's World Cup squad, have been hit by a pay row which caused coach Juan Carlos Oblitas to resign last week. He will be replaced by Argentine Edgardo Bauza.
Olmedo stayed top of the championship's second stage with 11 points from five games after drawing 2-2 at Aucas.
