Update: 11:20AM Goalkeeper Sergio Romero saved two penalties this morning to send Argentina into the World Cup final with a 4-2 shootout win over the Netherlands after the game finished in a 0-0 stalemate.
A day after Germany lit up the World Cup with its clinical 7-1 destruction of host Brazil, the Netherlands and Argentina could not manage a goal between them in 120 minutes before the shootout.
Romero - thought to be a weak link in this Argentine team and not even a starter for his Monaco club most of last season - blocked penalties by Ron Vlaar and Wesley Sneijder.
For Argentina, Lionel Messi, Ezequiel Garay, Sergio Aguero and Maxi Rodriguez all converted their spot kicks.
It was the second straight penalty shootout following a 0-0 draw for the Dutch.
Against Costa Rica in the quarterfinals, coach Louis van Gaal brought on substitute goalkeeper Tim Krul in the last seconds of extra time to replace Jasper Cillessen and Krul saved two efforts.
The young Ajax goalkeeper got a hand to Rodriguez's decisive powerful shot, but could only deflect it into the roof of the net, and then collapsed onto his back in the goal.
Krul walked across the pitch to console him and Van Gaal later gave him a pat on the back of the head.
Argentina, a two time World Cup winner, reached its fifth final, and its first in 24 years. It won the title in 1978 and 1986 and lost the championship matches in 1930 and 1990. It played West Germany in both the '86 and '90 finals.
The Netherlands, which has never won the World Cup, was seeking to reach its fourth final.
