Goals from Santi Cazorla and Cesc Fabregas in the first half proved sufficient to hand La Roja the win despite Wilde-Donald Guerrier's shock strike in the final 15 minutes, and Del Bosque feels the match was effective preparation for the upcoming FIFA Confederations Cup in Brazil.
"In the first half, I think we played to our level, we controlled the ball and created chances," Del Bosque told reporters after the match. "After the break we put less pressure on, played with less intensity and Haiti were able to see more of the ball and play better, but overall it was a good test for us."
Haiti goalscorer Guerrier had celebrated the birth of his son Cristiano - named after the Real Madrid superstar - the day before the game, and he was thrilled at the way his side showcased its ability against the world's finest side.
"It was a great honor to play against the world champions, and I think we showed that Haiti is not only about the earthquake we had, but we showed that we have talent," Guerrier said. "I was very pleased to get a goal against the No. 1 team in the world. They are great players, but they are human beings, they aren't from another planet."
Spain faces Ireland at New York's Yankee Stadium on Tuesday in a final warm-up game prior to the Confederations Cup, in which it will face Uruguay, Nigeria and Tahiti in Group B. Brazil, Mexico, Italy and Japan make up Group A.
