Four in a Row

There are six Americans who are member's of the 2012 Olympic team who have won medals at each of the three previous Games:

Jason Lezak, swimming - the author of on of the great moments in Olympic history when he miraculously overtook Frenchman Alain Bernard in the 4x100 meter freestyle relay in Beijing, Lezak has captured  medals at each of the three previous Olympic Games, all in relays.  A gold and silver in Sydney; gold and bronze in Athens and two gold plus a bronze in Beijing.  He will likely swim the freestyle relay heats in London.

Steven Lopez, tae kwon do - Lopez captured gold in Sydney and Athens before a disappointing silver in Beijing.  He captured five consecutive world championships from 2001 to 2009.  Lopez will once again be a contender for gold this year in London.

Christie Rampone, soccer - a member of the silver medal team in Sydney, Rampone has captured golds in Athens and Beijing and is the captain of the squad looking to capture a third straight gold in London.

Brenda Villa & Heather Petri, water polo - Villa leads the US women's water polo team that has captured medals at each of the last three Olympics, but will be looking for a first gold medal in London.

...and going back to Atlanta...

Kim Rhode, shooting - Rhode has won medals at each of the last 4 Olympic Games and she just turned 33 this week.  Rhode won the gold in the double trap event in Atlanta.  She followed with a bronze in Sydney; another gold in Athens; and finally a skeet bronze medal in Beijing.
