Argentina were held away from home in Ecuador, as Sergio Aguero's early penalty was cancelled out by a header from Segundo Castillo. The match was also notable for a bizarre red card for Javier Mascherano for kicking a medic. You can find the full match report here, and the video of the Mascherano incident here.
Colombia 2-0 Peru
Falcao and Teofilo Gutierrez got the goals as Colombia comfortably dispatched Peru at home, leaving them with only one more win required to secure their qualification and a place in Brazil.
Venezuela 0-1 Uruguay
Uruguay just about scraped a much-needed win in Venezuela through Edinson Cavani. The hosts are now in fifth place in the playoff spot, overtaking their opponents Venezuela on goal difference to end a miserable recent run.
Chile 3-1 Bolivia
David Pizarro returned for the hosts after a long absence from the national team, and marked the occasion with a fine display and a win. Eduardo Vargas opened the scoring before Alexis Sanchez's first international goal for almost two years doubled Chile's advantage. Marcelo Martins struck back for the visitors in the first half, but Chile held on, Arturo Vidal heading home in injury time to seal the result.
