Betsey Armstrong, Goalkeeper
According to the Los Angeles Times, Armstrong has a tattoo of an anchor on her right calf, and she's become one of the best anchors in the world as a goalkeeper.
Her teammate, Brenda Villa, had this to say about the stalwart goalkeeper: "She's our last line of defense. She leads by example. She does her job and she does it extremely well."
Armstrong has been universally recognized as one of the best water polo players, earning the Swimming World Magazine 2009 female water polo player of the year honors and the FINA 2010 female water player of the year, according to the team's media guide.
Elsie Windes, Defender
Windes is one of the leaders of this team, having played in every major championship over the last four years. She isn't a big-time goal scorer, though, and will spend most of her time playing scrappy defense in front of Armstrong.
That doesn't mean she's incapable of scoring, as Windes tallied six goals in the 2009 World Championships and 23 goals in 18 matches during her senior year at Cal Berkeley.
Kami Craig, Center
Craig is a terrific player. She won the Peter J. Cutino Award twice (the best collegiate player in the country) and is a deadly scorer from her center position.
She scored 12 goals in the team's Pan American showing, helping them earn the gold medal to automatically qualify for the 2012 Summer Games.
Craig also brings championship experience with her to Team USA, having won the 2010 National Championships with the USC Trojans.
Lauren Wenger, All-Around
Wenger returns to the team after a short absence in 2010 due to a sports hernia. At 6'3", she is an imposing figure in women's water polo, and she's one of the best players Team USA has to offer.
She is the most versatile player on the American team, and she can play every position in the pool except goalkeeper, according to NBCOlympics.com.
Wenger can do it all, and she'll need to be at the top of her game for the Americans to win the gold in London in 2012.
