Now to the world cup and that thrilling victory for team usa, avenging loss to Ghana in the last two world cups and we're going to show you an exhausted team usa arriving back to their hotel early, early this morning. Oh, ABC's bob woodruff has all the dramatic details from Rio, good morning, bob. Reporter: Well, good morning, robin. Yeah, an amazing might last night. You missed the party right down here on the beach where I actually lost my voice but there's no doubt about the United States because we are in the group of death. But last night, they certainly did not die, in fact, they made their point within half a minute. ? just 29 seconds into the game -- Dempsey scores. The U.S. Incredibly within seconds have scored. Reporter: Clint Dempsey takes it to the house. The absolute perfect start to the 2014 world cup. Reporter: The earliest U.S. Goal in world cup history, the fifth earliest ever in the world cup tournament. The electricity felt back home. Crowds gathering in cities like Chicago, Brooklyn, Baltimore, even our soldiers overseas in Afghanistan on their feet. Here in Rio, we jumped and took selfies. Praying about all day, just trying to step up for the team and I was glad I was able to do that today. Reporter: But minutes later the thrills turning to chills. Oh, no. Now that is a problem. Team usa star striker jozy altidore straining his left hamstring taking him out of the game. Then this -- Oh, that hurt from here. Dempsey down his nose busted and bleeding. Then late in the second half -- A goal to break American hearts. Reporter: Ghana pumping one in to tie the game then the I believe moment. It's brooks for the usa. Reporter: Defenseman rookie sub city toot John brooks with an incredible head story take the lead and ultimately the game. Payback for the usa. Reporter: With that, the beer started flying. I'm covered with beer. U.s. Team always has a great spirit and fights until the last second so it was a wonderful one at the end of the day. Reporter: Caught up with the still excited team back at their hotel. To be able to walk out on to a field in Brazil and have such amazing support from our American fans was incredible. Reporter: So remarkably John brooks says several days ago he had a dream that he was going to end this game by scoring and winning it for his team. Well, it turns out it was true. Robin. All right, bob, thank you very much. You can tell by his voice that he's been screaming a little bit out there. Long night for bob. We'll stay in Rio and talk to ESPN soccer analyst and former U.S. National team star alexei lalas. You said this U.S. Team is different than the one that lost in the last two world cups to Ghana. Boy were you right. To a certain extent they are different but when I look at this game it was awesome. Was it Progressive? Was it new? Absolutely not but I don't care. It was traditional. It was American in that the U.S. Didn't have a lot of possession. They defended like ban chis. They relied on set pieces. Jozy altidore going down. Clint Dempsey breaking his nose and in that sense for me it was beautiful. They got three points against a team that played better than them, but that's the only thing that matters is they got three points so, yes, for me it was a beautiful performance. You don't get to tell me what a beautiful woman is. You don't get to tell me what a beautiful song is or what a beautiful wine, I go et to decide and that was a beautiful performance. That was America. Ah, I love -- what's not to love about you, alexei. Let's talk a little bit more about the group. They have Portugal that they'll play on Sunday. Just tell us a little bit about that matchup. Well, look, Portugal is a great team. We know about Cristiano Ronaldo, the fact that Portugal went out in their first game and got shellacked by Germany. It could come down to the goal differential. There were a few injuries and a red card for Portugal so they'll be missing some of their key players but I tell you what, I think we'll see a better performance from the U.S. In terms of possession against Portugal but just because you beat Ghana doesn't mean you've gotten through the group and have to figure out a way to beat a very good Portugal team and have a good performance and a better performance against Portugal. This has to give them confidence, alexei. Absolutely, absolutely. How about John brooks? If you had told me, I don't know, a couple months ago John brooks would be on the team yet alone score that goal I would have told you crazy but that's what the cord cup is about. It can change your life and did for John last night. He had a dream about it. We'll talk to him later. Alexei, enjoy your day there. Thanks for stopping by. We appreciate it. Thank you very much. All right, ESPN has a triple header of world cup action starting at 11:30 eastern.
