While favourites Argentina and Brazil struggle for form, Chile and Peru are awakening from years of slumber at the Copa America football after moving closer to the quarterfinals on Friday.
Peru won the last of its two South American championships in 1975 in the halcyon days of the gifted Teofilo Cubillas, who would go on to prove a star turn at the 1978 World Cup.
Chile, meanwhile, has been bridesmaids at four finals but never the continental bride. That may change if promising star Alexis Sanchez has his way.
The Barcelona target scored to land a precious 1-1 draw with fancied Uruguay and leave the Chileans with four points - surely enough in practice to start looking forward to the last eight while Friday's rivals have work to do after a second straight draw.
Peru is joint leader of Group C with Chile, having earned four points of its own after Paolo Guerrero's second goal of the tournament saw off inexperienced Mexico 1-0 in Mendoza.
With both joint leaders having held Uruguay and defeated the Mexicans, regular special guests at the South American event, Peru and Chile can look forward to a Pacific clasico on Tuesday with the pressure largely off.
A draw will send both sides through while Uruguay will likely have to beat Mexico to ensure its own passage.
A third straight draw would leave Diego Forlans' Charruas, like Argentina chasing a record 15th title, perched on the precipice.
Sanchez, who plays for Italy's Udinese, came to the event trying hard to put aside reports of interest in his talents from European champion Barcelona.
But his instinctive finish just after the hour mark to level Alvaro Pereira's opener eight minutes into a lively second half served to underline the talent of the 22-year-old from Tocopillo.
Chile coach Claudio Borghi is emerging as the would-be purist at the championships as his side has turned in some of the most entertaining football compared to the sterile fare of the host and also holder Brazil.
“I prefer to draw playing in this fashion than to win playing badly,” insisted Borghi after seeing the Chileans end their encounter all-square.”
“Today was a good test for us, but we have achieved nothing as yet,” warned Borghi.
Uruguay coach Oscar Tabarez saluted Sanchez's finishing skills. “The goal came following a defensive mistake of ours, but Sanchez, who is a great player, took advantage,” said Tabarez.
Peru coach Sergio Markarian, a Uruguayan, shared Borghi's caution after Guerrero's close-range winner against the Mexicans.
“We have won nothing yet. The tournament only really gets going in the quarters. Getting there is our primary target,” said Markarian, whose side missed several good chances - Peru's Fiorentina star Juan Vargas hitting the woodwork - before Guerrero finally put the Mexicans out of their misery.
The results: Uruguay 1 (Alvaro Pereira 53) drew with Chile 1 (Alexis Sanchez 65); Peru 1 (Paolo Guerrero 83) bt Mexico 0. - Agencies
