Messi at the double as Argentina trounce Bolivia in Copa America
Lionel Messi in action.
Messi -- who had equalled Javier Mascherano's Argentinian caps record of 147 last week -- marked his 148th appearance in style, setting up the opening goal before bagging a brace of his own.
The victory at Cuiaba's Arena Pantanal stadium sees Argentina advance to a quarter-final on Saturday against Ecuador, the fourth placed finishers from Group B.
The Argentines almost took the lead after three minutes, only for Bolivia goalkeeper Carlos Lampe to pull off a remarkable double save from Sergio Aguero and Angel Correa in quick succession.
But Argentina reasserted their dominance and it was Messi who made it 3-0, latching on to a clever lofted pass from new Barcelona team-mate Aguero and lobbing a cheeky finish over the advancing Lampe.
Bolivia pulled a goal back in the 60th minute with a cleverly worked move, Chura's deft back heel releasing Leonel Justiniano down the right flanke who crossed for Erwin Saavedra to score.
Argentina responded swiftly though, substitute Lautaro Martinez tapping in from close range in the 65th minute just two minutes after coming on for Aguero.
In Monday's other Group A game, Uruguay clinched second place in the table after downing Paraguay 1-0 in Rio de Janeiro.
Edinson Cavani's first half spot kick proved decisive for 'La Celeste', sending Uruguay into a quarter-final against Colombia on Saturday.
Paraguay finished third and will now play Peru on Friday. Chile, who finished fourth in Group A, face a daunting task against hosts Brazil on Friday.
