Tim Howard and Bryan Oviedo remain on course for next summer's World Cup after the latest qualifying action.
Howard was in action for the United States on Tuesday evening, keeping another clean sheet as the group leaders prevailed 1-0 over Honduras in Sandy, Utah.
Meanwhile, second place Costa Rica emerged victorious in San Jose, beating Panama 2-0.
Oviedo, omitted from the national squad for the recent fixtures, will be hoping for a recall in time for 2014's big spectacle in Brazil.
The top three teams in the North, Central America and Caribbean group automatically qualify, with the fourth-placed side entering an Intercontinental Play-Off against Oceania winners New Zealand.
