USA keep on cruising

Chris Bosh scored a team-high 20 points as the red-hot tournament favourites preserved their perfect record in Group D against winless Senegal in Sapporo.

U.S. coach Mike Krzyzewski gave his starters significant minutes on the bench ahead of the 16-team knockout phase which begins in Saitama on Saturday.

The Americans still powered to a 58-24 halftime lead and never extended themselves over the final two quarters in what was little more than a light workout for the team's NBA stars.

The U.S. finished an embarrassing sixth at the last world championship in Indianapolis in 2002 and had to settle for bronze at the 2004 Athens Olympics.

They won the last of their three world titles in 1994 and their last Olympic gold medal at the 2000 Sydney Games
