Last summer, after losing to Japan in the World Cup, Abby Wambach guaranteed Olympic Gold for 2012.

And she delivered.

"It's an absolutely amazing experience, it's just so great to see my sister out there having a wonderful time," says Andrew Wambach, Abby's brother.

More than 80,000 people witnessed the gold medal win in London's Wembley Stadium, but the local crowd was cheering hard alongside them.

"I thought it was going to be a nail-biter," said Andrew. "And it was."

The U.S. started with an early lead of 1-0 against Japan but continued to side step some game changing moments like Japan stealing the ball in the final 10 minutes, before a diving save by Hope Solo kept the U.S. in the lead.

"You can never be too comfortable," says another brother of Abby, Peter Wambach. "All it takes is one kick from half field."

Midfielder Carli Lloyd scored both of team U.S.A.'s goals. Wambach's brothers said Abby played very well and stuck to the game plan during the championship game.

A forward for the U.S. team, Wambach grew up playing sports with her six siblings in Rochester.

"We grew up on a cul-de-sac and played hockey and football and swam all day long,' said Peter.

Even giving her older brothers some stiff competition,

"When it came time to pick a team she wasn't the last to be picked," said Peter. "Even for football, she was tough and you can see that by how she plays today."

This was not only a win for the USA, but Rochester as well. Family, friends and even past competitors of Wambach came to show their support and sang the National Anthem as a community, when the American flag was raised.

"Anybody that just wanted to show up did and that's great to see," said Peter. "Giving them the opportunity to experience what we always experience every game."
