Striker Jozy Altidore scored twice as the United States thrashed Trinidad and Tobago 4-0 on Tuesday to book their place in the final round of the CONCACAF region's 2018 World Cup qualifiers.
Altidore scored twice in four minutes midway through the second half, either side of goals from Sacha Kljestan and substitute Paul Arriola to confirm an emphatic win for the hosts at EverBank Field in Jacksonville, Florida.
Jurgen Klinsmann's side had needed only a point to be sure of reaching the final round of qualifiers for CONCACAF.
The USA took the lead in the 44th minute when neat interplay down the right flank involving Fabian Johnson, Kljestan and Pulisic sowed confusion in the Trinidad box.
Khaleem Hyland made a mess of his clearance from Pulisic's low cross, diverting the ball into the path of Kljestan who drilled home a low finish.
Borussia Monchenglad-bach fullback Johnson was involved in the build-up for the second on 59 minutes, his pass finding Altidore just inside the penalty area.
