That changed on Wednesday as the U.S. jumped out to an early lead en route to a 79-55 rout of Australia in its quarterfinal matchup at the Tokyo Olympics. The fast start helped secure a spot in the Final Four as Team USA extended its winning streak to 53 games and put itself within two victories of a seventh straight gold medal.
