"It's always good to be back here — to be back with the boys," Wood said.
Having become a regular in the starting lineup alongside Jozy Altidore, Wood missed a pair of qualifiers in March due to his aching back, which he said is still "a little bit naggy here and there," but calmed through treatment and exercise.
"I'm healthy," he said.
Introduced to soccer while growing up in Hawaii, he didn't know the importance of World Cup because, "back in the day, they didn't show so much soccer. You didn't have it all the time on normal TV. It was more difficult to get all that information on the island."
Naturally, his feelings have intensified.
"I'm honored to have the chance to possibly be at the World Cup," Wood said. "I'm going to give it my all and try and help the team get there."
While he was sidelined, the U.S. earned a win and a draw to move into fourth place in the six-team final round of North and Central America and the Caribbean. There are six games remaining, and the top three teams qualify for next year's tournament in Russia. The fourth-place squad will go to a playoff against Asia's No. 5 nation.
"I was pretty confident the team would get the job done," said Wood, who was bothered by knee injuries earlier in his career that had him considering stepping away from soccer. "I thought they did a really good job getting the result."
Wood is one of four forwards competing for playing time, along with Altidore, Jordan Morris and Clint Dempsey, who also could be dropped into an attacking midfield role. Wood has been soaking up as much knowledge as he can from Dempsey, who is one goal from tying Landon Donovan (57) for most in U.S. national team history.
"You can learn a lot from an experienced player," Wood said. "That's why he's there. I'll try to pick off whatever he's got for me."
Not that long ago, the 24-year-old Wood met with U.S. coach Bruce Arena in Germany to discuss the expectations for him and the team.
"Very smooth, direct," Wood said of their meeting. "It was good."
Just be himself: That was essentially Arena's message.
"He's a little different than our other strikers. That's a real plus," Arena said. "The four guys we're going to have in camp, they're good strikers and we can certainly utilize all of them."
