The United States men and women put on a show in their first games at the FIBA 3x3 Olympic Qualifying Tournament in Graz, Austria.

The U.S. women got off to a hot start just days after winning Sunday's Big Twelve International Tournament in France. Following a 21-7 rout over Indonesia, the quartet of Allisha Gray, Stefanie Dolson, Katie Lou Samuelson and Kelsey Plum went on to take down France, the top-ranked women's 3x3 team in the world, by a score of 21-17.

Team USA also defeated France to win the Big Twelve International Tournament.

The men began the tournament with a perfect 2-0 record as well. After a close 21-20 victory over Lithuania, the U.S. team of Robbie Hummel, Kareem Maddox, Dominique Jones and Joey King dominated South Korea en route to a 21-3 shellacking to cap their first day of competition.

The men will resume play Saturday when they take on Kazakhstan and Belgium. The women will also resume play Saturday, beginning with a game against Germany followed by a meeting with Uruguay.

Both teams will need to finish within the top three of the tournament in order to qualify for the Tokyo Olympics.
