The U.S. hopes a blowout win over the world's 100th-ranked team can start to lessen the pessimism created by the Americans' longest losing streak since 2007.
Malik Tillman scored twice and Diego Luna had a pair of assists in a 5-0 rout of Trinidad and Tobago on Sunday in the Americans' CONCACAF Gold Cup opener.
"Really important I think to cut a little bit this - I don't say negativity, but, yes ... but it's really important now to start the competition with a good feeling," U.S. coach Mauricio Pochettino said.
Victory in the Group D opener ended a four-game losing streak and came after days of controversy over Christian Pulisic's desire to rest during the Gold Cup and Pochettino not including the star in a pair of pre-tournament friendlies the attacker offered to play in.
Tillman scored in the 16th and 41st minutes for his first two international goals, both following giveaways by Alvin Jones, and Patrick Agyemang scored his fourth international goal in the 44th when Luna's shot deflected off a foot.
