Wondolowski obliged, continuing his torrid goal-scoring pace with two more in the final 45 minutes of Saturday's match to give the U.S. a 4-1 win over Cuba.
"I wanted to be ready and add as a spark when I came off there," Wondolowski said.
The striker praised his U.S. teammates including Real Salt Lake midfielder Kyle Beckerman, who assisted Wondolowski for a second time in two games for the streak.
"The guys are playing so well right now and creating a lot of opportunities," Wondolowski said after being named man of the match Saturday at Rio Tinto Stadium. "I'm just fortunate to find myself on the end of some."
But Klinsmann said Wondolowski's work in practice has finally paid off internationally.
"It's just a joy to see him every day in training, and now he's getting his goals that he was waiting for such a long time for," Klinsmann said. "Now they're coming."
Wondolowski, Major League Soccer's Golden Boot winner a year ago, scored in a warmup against Guatemala before exploding for three against Belize and then finding two more Saturday against Cuba. His six for the U.S. is one more than the five he's tallied in 17 games for his club this season.
His international goals have come against lesser opponents. Next week against Costa Rica will surely provide a greater test for Wondolowski, but the striker is looking to continue his hot streak.
"Striker is a funny position," Wondolowski said. "Sometimes goals don't come, anything you hit goes off the post, keepers make saves. Sometimes you get a toe on it and it goes in. I want to try to go and keep it going."
