Arsenal de Sarandi joined Group Eight winners Santos Laguna in the last 16 of the Copa Libertadores after earning a 3-1 victory at Anzoategui of Venezuela. The Argentinian visitors broke the deadlock in emphatic style in the 35th minute through Matias Sanchez's long-range strike although Rolando Escobar levelled matters early on in the second half.
However, Arsenal were back in front in the 65th minute through playmaker Martin Rolle and Matias Zaldivia scored in stoppage time to seal their place in the next stage for the first time in their history. With one round left to go, Arsenal are five points clear of third-placed Penarol in the standings, but four behind Santos Laguna.
Velez Sarsfield boosted their hopes of qualifying for the last 16 by going three points clear at the top of Group One following a 3-1 victory at Atletico Paranaense. Agustin Allione gave the Argentinian visitors a seventh-minute lead before Paranaense levelled matters after 55 minutes through substitute Drausio's header, moments after Fran Merida had been dismissed from the bench.
The Brazilians started to get on the front foot but were hit with a sucker-punch on the hour mark when Lucas Pratto put Sarsfield ahead once more and although the visitors had Emiliano Papa sent off, they increased their lead through Hector Canteros's effort from distance.
Former France striker David Trezeguet scored twice as Newell's Old Boys came from behind to beat nine-man Nacional 4-2 and move to the top of Group Six. Juan Mascia put the Uruguayan hosts ahead in the 11th minute before strikes either side of half-time from Alexis Castro and Marcos Caceres put Newell's in front, only for Andres Scotti to level proceedings from the spot just after the hour.
But Nacional's hopes took a blow when Rafael Garcia saw red and Trezeguet, a 66th-minute substitute, made a tremendous impression with two goals in the final 15 minutes, with home goalkeeper Jorge Bava also sent off in-between.
In Group Three, Nestor Camacho's last-gasp goal gave Deportivo Cali a 1-1 draw against O'Higgins, who had opened the scoring through Yerson Opazo. Finally, Bolivar moved above Leon of Mexico to the top of Group Seven as Willian Ferreira's wonderful shot from outside the box gave the Bolivian side a 1-0 win.
