Uruguay defeated Peru 4-2 on Sunday to move into second place in South American qualifying for the 2014 World Cup.
The hosts took the lead in controversial fashion after 15 minutes as centre back Sebastian Coates' goal-bound header looked to be blocked on the line by Peru's Antonio Gonzales and despite the protests, the goal was awarded.
Maximiliano Pereira soon doubled the lead much to the delight of the Centenario crowd, but the visitors were soon back on level terms thanks to an own goal from Uruguay defender Diego Godin and a volley from striker Paolo Guerrero either side of the interval.
Diego Forlan had a penalty saved by Peru's Diego Penny, but the Uruguayans romped home with further goals from substitutes Cristian Rodriguez and Sebastian Eguren in stoppage time to complete their third four-goal haul in five matches.
The win lifted Copa America holders Uruguay into second place, a point behind leaders Chile and one ahead of Argentina.
Meanwhile, Ecuador enjoyed a 1-0 win over Colombia in Quito thanks to striker Cristian Benitez's 54th-minute header, despite having defender Christian Noboa sent off late on.
The three points saw them climb to fourth spot in the standings.
The top four teams will automatically secure a World Cup spot, while the fifth-place nation advances to an intercontinental playoff.
