Needing to win by three goals, Guatemala coach Ever Hugo Almeida told his players to ignore the big picture and focus on one at a time.
They made it — with one to spare.
Marco Pappa had a goal and an assist and Guatemala beat Grenada 4-0 Monday night to clinch its first trip to the CONCACAF Gold Cup quarterfinals since 2007.
"More than anything, this was a psychological and mental game," Almeida said. "We had to score a specific number of goals. We needed three goals, but we had to take it goal by goal. We were able to manage the game and get the result we wanted."
Jose Del Aguila, Carlos Ruiz and Carlos Gallardo also scored for Guatemala, which finished third in Group B after Jamaica beat Honduras 1-0 later in the evening. It had a plus-2 goal difference to top Group A's third-place finisher, El Salvador, which also had four points but an even goal difference.
Guatemala, ranked No. 124 in the world, will not know where it will play until Wednesday, when Group C finishes. The results also will determine whether El Salvador advances.
Canada will play Panama and the United States will face Guadaloupe in Tuesday's games.
Guatemala either will play Saturday at the New Meadowlands Stadium or Sunday at RFK Stadium in Washington.
That didn't worry Pappa.
"Now, we have to think about the next match," the Chicago Fire forward said.
No matter what happens in the knockout round, Almeida said the team has achieved all its goals heading into the Gold Cup competition.
"At this moment, we're very happy," Almeida said. "We were able to qualify, and that's what we came for. Now we'll wait and see who we play, whoever it is."
Guatemala lost 3-0 to Canada in its previous appearance in the Gold Cup quarters. But it capped a 1-1-1 performance in this year's group competition with a stellar showing against 98th-ranked Grenada.
Del Aguila and Pappa scored in the first half. Jairo Arreola's shot went off the crossbar and Ruiz knocked it in to make it 3-0 in the 54th minute. Pappa fed Gallardo from the side of the box for a shot past goalkeeper Shemel Louison in the 59th minute.
Grenada finished last in Group B, losing all three of its games by a combined score of 15-1. It has been outscored 25-1 in two Gold Cup competitions.
"We realistically felt we could get third place and get into the quarterfinal through the back door," Grenada coach Mike Adams said. "But the intensity the game is played at this level came as a big surprise to us. It's a big step up from the Caribbean Cup. It was a case of not being able to sustain it."
