Leading an American sweep of the podium, Mariel Zagunis, who helped Notre Dame to a fencing national championship in 2005, won the gold in individual saber over teammate and countrywoman Sada Jacobson.  You might remember Mariel from 2004, when she also won the gold medal, becoming the first individual to win gold medals in back-to-back Olympics since some French guys in the 80's (that's a rough citation of what the color commentator said after her victory). 

USA!  USA!  USA!  USA!
