Argentina 0 Colombia 0 (5-4 on penalties): Messi and Co. advance despite Ospina's heroics

Argentina have edged their way into the Copa America semi-finals via a penalty shootout after their match against Colombia ended scoreless.

Carlos Tevez scored the decisive penalty with Argentina's seventh spot-kick after Lucas Biglia and Marcos Rojo both missed opportunities to claim victory on Friday.

The Arsenal gloveman's biggest moment was an amazing double save in the 26th minute when he denied Sergio Aguero with his foot before scrambling to palm Lionel Messi's follow-up header around the post, with both shots coming from inside the six-yard box.

Romero made just one save throughout the 90 minutes but was impressive in the shootout before Tevez - who was confirmed as a Boca Juniors player during the game - sent Argentina into the last four.

It took just five minutes for Ospina to register his first save with the 26-year-old getting down low at his near post to parry Javier Pastore's toe-poke.

With Mejia playing as Colombia's sole defensive midfielder, Pekerman's men were overrun in the middle.

James Rodriguez wasted an opportunity to shoot in the 67th minute, before Martinez produced Colombia's only shot on target, heading straight at Romero from a corner.

Argentina hit the woodwork twice late in the game, with substitute Ever Banega clipping the crossbar before Ospina produced another stunning stop - palming Nicolas Otamendi's effort onto the post.

Eventually penalties were required, with the first six spot-kicks finding the net before Luis Muriel blasted over the bar with Colombia's fourth.

After Ezequiel Lavezzi scored off the post, Romero almost denied Cardona but the midfielder's penalty squeezed under him before Biglia missed to send the shootout into sudden-death mode.

The next three penalty-takers failed to score with Romero denying Zuniga before Rojo clipped the bar and Murillo matched Muriel's effort, with Tevez calmly converting to decide the game.
