PARIS (Reuters) - Argentina earned a 3-1 win over Iraq in Lyon and Spain outclassed the Dominican Republic 3-1 in Bordeaux in the second matchday of the men's Olympic soccer tournament on Saturday.
Argentina recovered from their chaotic opening loss to Morocco and boosted their chances of reaching the next round as they went top of Group B on goal difference.
Debutants Dominican Republic's first Olympic goal was not enough to stop the Spaniards who scored twice in the second half to clinch a quarter-final spot with their second Group C win.
Argentina opened the scoring after 14 minutes thanks to a Thiago Almada's volley after Julian Alvarez set him up but Iraq captain Aymen Hussein equalised seconds before halftime with a brilliant header.
Substitute Luciano Gondou restored Argentina's lead with a close-range finish before a superb strike by Ezequiel Fernandez six minutes from time secured all three points for the 2004 and 2008 gold medallists.
Spain dominated from the early stages and went ahead in the 24th minute when Fermin Lopez pounced on a poor clearance by the Dominican goalkeeper to score.
Angel Montes de Oca equalised with a towering header from a corner in the 38th minute but the Dominicans' hopes of a shock suffered a major blow with Edison Azcona's red card for a foul on Pau Cubarsi.
Alejandro Baena restored Spain's lead when his long-range strike deflected off an opponent into the net and Miguel Gutierrez's tap-in into an empty goal sealed victory.
Hosts France, Israel, Japan and the United States are in action later on Saturday.
