Colombia moved within a point of Uruguay with a convincing 4-0 win. Atletico Madrid striker Falcao put the hosts ahead in the second minute, Teofilo Gutierrez padded the lead with two goals in four minutes early in the second half and Camilo Zuniga added a fourth in stoppage time.
Ecuador struggled past lowly Bolivia 1-0, with the sole goal coming in the 74th minute when substitute Felipe Caicedo converted a penalty. Ecuador moved up to third in the standings while Bolivia is only above last-placed Paraguay on goal difference.
Peru won 2-1 at home against Venezuela to move out of last place while dropping Venezuela out of the top five. Juan Arango had put Venezuela ahead in the 43rd minute, but the hosts quickly repaired the damage in the second half, as Jefferson Farfan scored in the 47th and 59th minutes. The visitor's chances of mounting a comeback were dashed when Gabriel Cichero was sent off in the 67th.
Qualifying resumes on Tuesday with Argentina away to Peru, Uruguay hosting Ecuador, Chile at home against Colombia and in the Chilean capital of Santiago and Paraguay travelling to Venezuela.
