Uruguayan giants Penarol closed in on a place in the Copa Libertadores last 16 as a 2-1 win over Argentinian side Godoy Cruz took them to the top of Group 8.
Juan Manuel Olivera opened the scoring for Penarol three minutes before half-time after pouncing on a loose ball following a corner, but a 57th-minute own goal by Dario Rodriguez brought the teams level. Godoy Cruz presser for a winner but were caught on the counter-attack and Nicolas Freitas scored the 70th minute winner.
Penarol will be certain of a place in the next stage if they avoid defeat against another Argentinian side, Independiente, in the final round of group games, but could qualify even if they lose.
Godoy Cruz, currently second in the group, face a tough away game at high altitude against Liga de Quito in their final group fixture.
