The Senegalese women's basketball team was given a rude welcome to the Rio Olympics by a merciless U.S. squad on Sunday.

The Americans jumped all over Senegal from the start, sprinted to a 33-7 lead in the first frame, and never took their foot off the pedal en route to a 121-56 beatdown.

Their 121 points marked a new women's Olympic single-game record, besting the previous high of 114. It was also the largest margin of victory in U.S. women's basketball history.

The U.S. employed a swarming defensive strategy, pressuring the ball and forcing a cavalcade of turnovers from their rattled opponents. Those turnovers led to fastbreak after fastbreak the other way, which contributed to the U.S.' shooting a ridiculous 66 percent from the field.

When they weren't running off live-ball turnovers, the U.S. whipped pinpoint passes all around the floor, from the post to the wing to the corner and back, finding slashers and open 3-point shooters and leaving Senegal's defense a pile of shredded ribbon.

It was a balanced scoring attack from the U.S., who had seven players score in double figures, led by Sylvia Fowles' 17. Diana Taurasi nailed five 3-balls as the U.S. shot 56 percent from deep, and Sue Bird dished out eight of the team's 31 assists.

The U.S. should face a stiffer test on Monday, when they resume Group B preliminary play against world No. 3 Spain.
