A dominant performance from Ricardo La Volpe's team saw them dispatch the South Americans, who had two men sent off in the second-half
Second-half goals from Josue Martinez and Joel Campbell gave Costa Rica a vital 2-0 win against Bolivia, who ended the game with nine men.
It could easily have been more for Ricardo La Volpe's side, who hit the woodwork twice, missed a penalty and threatened to run riot during the second 45 minutes with a two-man advantage.
With the majority of the fans inside the Estadio 23 de Agosto wearing green, it was perhaps no surprise that Bolivia were the more composed side during the opening exchanges. They created the first real chance of the game in the 13th minute, when Juan Arce’s low cross caught the Costa Rican defence flat-footed but just missed the boot of the onrushing Marcelo Moreno.
After being largely restricted to hopeful punts up field, Costa Rica almost took a surprise lead on 28 minutes, when Ronald Raldes rose high to block Martinez’s goal-bound header. They had another chance two minutes later, when Campbell’s brilliant through ball found Diego Madrigal one-on-one with the goalkeeper, but his dreadful first touch sent the ball closer to the centre circle than to the goal.
This seemed to spark the Costa Ricans into life and they finished the first-half strongly with a newfound willingness to run at the Bolivian defence. This approach nearly paid off in the 39th minute, when Campbell’s trickery created space at the top of the box, but his shot went straight into the arms of Carlos Arias.
La Volpe's team eventually took the lead with a scrappy goal on the hour mark. Substitute Allen Guevarra did well to turn Raldes inside the box and squeeze a shot towards goal. Arias could only parry it in front of him, and Martinez reacted the quickest to poke the ball home.
Five minutes later, the Central Americans nearly doubled their advantage when Campbell was brought down on the edge of the box by Ronald Rivero after a barnstorming run from midfield. Rivero received a yellow card, and Campbell himself stepped up to take the free kick, only to see it cannon back off the crossbar.
Bolivia were severely on the back foot at this point, and nearly threw the game away in the 70th minute. With the goal open following a one-on-one between Martinez and Arias, Rivero handled Mora’s goal-bound shot in the box and was shown his second yellow card. Guevarra stepped up to the spot, but Arias produced a stunning double save, first from the penalty and then from Guevarra’s attempted rebound.
Bolivia were down to nine men in the 77th minute after Walter Flores was sent off for a challenge on Campbell on the edge of the area. It could have gotten even worse for Bolivia, but Francisco Calvo crashed the resulting free kick off the post.
Costa Rica doubled their advantage two minutes later, after a great through ball by Mora found Campbell clean through on goal. The striker calmly finished into the corner to claim a deserved goal after a thoroughly impressive performance. Costa Rica played out the rest of the match with consummate ease, with Bolivia struggling to keep up given their two-man deficit.
Costa Rica now sit in second place in Group A on three points, one ahead of Argentina, who they play in four days' time during the final round of group matches. Meanwhile, Bolivia sink to last place with a solitary point and face group leaders Colombia on Sunday.
