The United States men's basketball team are bending, but they are not yet broken after edging France at the Rio Olympics.
USA escaped group play unbeaten on Sunday with a 100-97 victory over France.
Led by the shooting of Klay Thompson, who snapped out of an Olympic-long slump with a game-high 30 points, USA secured the top seed for the knockout stage, which promises an even greater challenge.
Serbia were too good for China 94-60 and Australia cruised past Venezuela 81-56.
USA's women continued their dominance in Rio continued with a 105-62 thrashing of China.
Elsewhere in Group B, Alba Torrens led Spain's women past Canada 73-60 and into the quarter-finals.
Serbia also beat Senegal, 95-88, to join Spain, Canada and USA in the next round.
One of Kyrie Irving's 12 assists, which tied a Team USA single-game record, was particularly impressive. In the fourth quarter, with USA nursing a four-point lead, the Cleveland Cavaliers star threw up a blind pass while falling forward into the hands of a leaping Kevin Durant, who buried a highlight-reel alley-oop.
MVP OF THE DAY
Chris Goulding came off the bench for Australia and contributed 22 points against Venezuela.
"Everyone wants us to win by a lot of points, but that's not going to happen this time, so we've got to be prepared for a grind-out game and I think we showed the last few games we can grind it out. It's game sevens from now on," - Durant on USA's string of close calls.
"I think it's probably more physical here. The NBA is more open, open space and bigger court, where this is more of a grind," - Australia's Matthew Dellavedova said of the difference between the NBA and international competition.
Group B is up for grabs Monday with all six teams separated by a mere two points. A renewal of the Argentina-Spain rivalry headlines the slate, with hosts Brazil on the verge of missing the quarter-final cut in a must-win game against Nigeria. Croatia, the tournament's biggest surprises, can clinch progression by beating second-place Lithuania.
The elimination stage is already set for the women, whose quarter-finals begin on Tuesday.
