Piero Alva's 39th-minute goal gave Peru their first win of the South American qualifying series against Venezuela in Lima. Peru now move onto six points and off the bottom of the standings, overtaking Bolivia.
Uruguay scored a crucial 1-0 away win over Colombia in Bogota, thanks to a 15th-minute goal from Sebastian Eguren. The Charrua now stand third in the South American qualifying section for the 2010 FIFA World Cup South Africa™, from which the top four teams progress automatically to the finals.
Argentina very nearly lost to Paraguay at the Monumental in Buenos Aires, but managed to right the ship enough to pull off a much-needed draw.
Gabriel Heinze scored an own goal in the 13th minute, but Sergio ‘El Kun' Aguero - fresh off a fine showing at the Olympics in Beijing - came to Argentina's rescue to equalise one minute after the hour mark.
Carlos Tevez was sent off on 31 minutes, making the result all the more impressive for the Albiceleste, who stay in second place in the South American qualifiers with 12 points, two less than pack leaders Paraguay.
The night's second game saw Ecuador stroll past Bolivia 3-1 in Quito. Felipe Caicedo, Edison Mendez and Cristian Benitez did the scoring for the home side, Joaquin Botero adding a bit of consolation in a game that was always beyond the Bolivians.
The win sees Ecuador move up one place into seventh in the South American table, while Bolivia - looking a shadow of their former selves - are one point off bottom.
